The project scope entails the full replacements of three bridges (BIN5500719, BIN5500739, and
BIN5500050) including demolition of the existing structures and construction of the replacement
bridges.
Saw Mill River Parkway (SMRP)
Saw Mill River Parkway (SMRP) will be constructed in four stages:
Stage 1
Stage 1 entails preparation for the first traffic shift. Nightly lane closures will be used to remove the
existing median guardrail and curb, and place temporary pavement for our trafficcrossovers. During this
stage, temporary widening on the southbound side of the BIN 5500719 Bridge and temporary pavement
along existing southbound SMRP will be done to help accommodate the required two lanes of traffic.
Temporary and permanent drainage crossings of the southbound roadway willalso begin to be installed
to facilitate the permanent drainage installed in Stage 2.
Stage 2
Stage 2 construction will start on the northbound direction by placing trafficinto an interim head-to-head
configuration along the existing southbound lanes. The northbound I-87 exit ramp will be temporarily
closed in this stage. Demolition and construction will begin on the northbound halves of BIN 5500719
and BIN 5500739 bridges. A temporary GRES wall will be constructed along the SMRP from stations
+/- 6'
526+50 to 538+50 to accommodate the difference in elevation from the new to existing roadways.
The northbound I-87 exit ramp willbe closed during this stage to adjust the grades to the new elevated

a 2
roadway. Staging will occur at the north end of the site within NYSDOT right-of-way to avoid flood prone
areas. Once construction of the two northbound halves of the structures is completed, the northbound
SMRP will be brought to its final grade and paved with base and intermediate courses.
Stage 3
Stage 3 begins with both directions of traffic shifting from the existing southbound lanes to the newly
constructed northbound lanes. The northbound I-87 exit ramp will then reopen. Once traffic is in its
second interim head-to-head configuration along the newly constructed northbound lanes, construction
will begin on demolishing and constructing the southbound halves of BIN 5500719 and BIN 5500739.
During this stage the southbound SMRP will be brought to its final grade and paved with base and
intermediate courses. Material will be staged similarly to that during the construction of the northbound
lanes.
Stage 4
Stage 4 starts once construction of both the northbound and southbound halves of the structures and
roadway is complete. Traffic will be shifted to the outer lanes of both directions of the roadway to allow
for closure pours to occur at both bridges, bridge median barrier to get completed and restoration of the
temporary median crossovers installed in Stage 1. Traffic willthen be placed into itsfinal configuration,
allowing for the final lift
of asphalt paving to occur utilizing night lane closures.
East 3rd Street Bridge
East 3rd Street Bridge requires four stages for construction:
Stage 1
The firstactivities to occur during Stage 1 are the early utilityrelocations and the temporary alignment
construction. There are two groups of utilityrelocations during this stage. The first group of utility
24"
relocations entail relocating the Mt. Vernon sanitary sewer line, the Westchester County sewer, a
portion of the flood wall that goes underneath the temporary bridge and the fire hydrant at the southeast
corner of Hutchinson Avenue and East 3rd Street in order to construct the approaches to the temporary
bridge. The second group of utility relocations that begin in this stage entail relocating the Consolidated
12"
Edison (ConEd) gas line and electrical lines in order to have relocation occur outside of the ConEd
no-work windows for both electrical and gas. Relocating the gas line prior to the seasonal window is
critical to avoid having to leave the line,and therefore the bridge, in itsexisting location untilthe seasonal
window liftsin April.
Occurring concurrently with the utility relocation is the construction of the temporary bridge approaches
from Hutchinson Avenue and Carol Avenue to the temporary East 3rd Street Bridge location. Once
construction of the temporary approaches reaches itsapproximate final elevation, construction of the
temporary bridge will begin. The temporary bridge willbe constructed at the western approach and be
launched to land at the eastern approach. The temporary bridge willbe constructed and launched in
segments during a weekend closure of the HRP. Once the temporary bridge is in place, relocation of the
remaining utilities on to the temporary bridge will occur. After completing the temporary bridge
approaches and paving, traffic will be switched to the temporary alignment and the existing 3rd Street
Bridge will be closed.
Stage 2
Stage 2 begins with demolition of the existing bridge, including stone removal and asbestos abatement.
Demolition can only occur once all utilities have been removed and traffic has been placed onto the

temporary bridge. Demolition of the existing bridge will occur during weekend directional closures of the
HRP. Removal of the existing East 3rd Street Bridge is the predecessor for work to begin along the HRP.
Due to our ATC 2, work can begin prior to the removal of the existing structure, but ultimately we chose
not to as itwould introduce additional staging along the HRP.
Stage 3
Stage 3 can begin once traffic is on the temporary bridge and the existing bridge has been demolished.
The proposed East 3rd Street Bridge will be constructed in a single phase using Accelerated Bridge
Construction (ABC) methods. Once the bridge superstructure elements have been completed, the East
3rd Street Bridge roadway approaches and final relocations of the Verizon and Extenet utilitieswill be
completed. With the final paving complete traffic will be switched to the new East 3rd Street Bridge.
Staging for this site will use the southbound HRP Exit 10 ramp gore area, as well at the Wolfs Lane ramp
area.
Stage 4
Stage 4 starts once the East 3rd Street Bridge is complete and traffic is shifted to its final location.
Removal of the temporary elements starts with the de-launching of the temporary superstructure, which
will occur using a weekend closure of the HRP. Following the de-launch will be the removal of the
temporary substructures, removal of the approaches, and the final grading of the site.
Hutchinson River Parkway (HRP)
Hutchinson River Parkway (HRP) will be constructed in four stages and will begin after Stage 2 of East
3rd Street Bridge sequencing.
Stage 1
Stage 1 begins behind temporary barrier along the southbound shoulder of HRP with the scopes of
20"
relocation of the Westchester County Sanitary line, relocation of the Hutchinson River, installation of
the ATC 2 and installation of the storm drainage trunk line.Once the trunk line is non-
floodwall, installed,
peak hour lane closures will be used to install the drainage crossings. Lanes will be returned to their
existing capacity during peak hours. Material will be stored behind barrier along the river and at the
southbound HRP Exit 10 ramp gore.
Stage 2
The next stage of HRP construction, Stage 2, is focused on construction of the median of the proposed
HRP. Work begins in this stage when drainage and paving of the southbound shoulder is complete and
can accommodate traffic to be relocated to it.Work in this stage includes demolition of the existing
median, installation of the median drainage system and median barrier construction. Once the median
barrier has been completed, milling and paving of the southbound roadway will commence under off-peak
hour lane closures. Installation of the drainage laterals crossing the northbound roadway occur in this
stage under off-peak hour lane closures.
Stage 3
Stage 3 moves to the northbound lanes of HRP. Work in this stage includes the drainage trunk line,
northbound shoulder and acceleration lane including curbs, underdrain, pavement and guard railing.
These activities are expected to occur during typical construction hours. Once the shoulder curb has been
completed, milling and paving of the northbound roadway will commence under off-peak hour lane
closures.

Saw Mill River Parkway (SMRP) Saw Mill River Parkway (SMRP) will be constructed in four stages: Stage 1 Stage 1 entails preparation for the first traffic shift. Nightly lane closures will be used to remove the existing median guardrail and curb, and place temporary pavement for our trafficcrossovers. During this stage, temporary widening on the southbound side of the BIN 5500719 Bridge and temporary pavement along existing southbound SMRP will be done to help accommodate the required two lanes of traffic. Temporary and permanent drainage crossings of the southbound roadway willalso begin to be installed to facilitate the permanent drainage installed in Stage 2. Stage 2 Stage 2 construction will start on the northbound direction by placing trafficinto an interim head-to-head configuration along the existing southbound lanes. The northbound I-87 exit ramp will be temporarily closed in this stage. Demolition and construction will begin on the northbound halves of BIN 5500719 and BIN 5500739 bridges. A temporary GRES wall will be constructed along the SMRP from stations +/- 6' 526+50 to 538+50 to accommodate the difference in elevation from the new to existing roadways. The northbound I-87 exit ramp willbe closed during this stage to adjust the grades to the new elevated 2 EECRUZ007399 FILED: NEW YORK COUNTY CLERK 10/28/2022 05:53 PM INDEX NO. 652321/2020 NYSCEF DOC.

Staging will occur at the north end of the site within NYSDOT right-of-way to avoid flood prone areas. Once construction of the two northbound halves of the structures is completed, the northbound SMRP will be brought to its final grade and paved with base and intermediate courses. Stage 3 Stage 3 begins with both directions of traffic shifting from the existing southbound lanes to the newly constructed northbound lanes. The northbound I-87 exit ramp will then reopen. Once traffic is in its second interim head-to-head configuration along the newly constructed northbound lanes, construction will begin on demolishing and constructing the southbound halves of BIN 5500719 and BIN 5500739. During this stage the southbound SMRP will be brought to its final grade and paved with base and intermediate courses. Material will be staged similarly to that during the construction of the northbound lanes. Stage 4 Stage 4 starts once construction of both the northbound and southbound halves of the structures and roadway is complete. Traffic will be shifted to the outer lanes of both directions of the roadway to allow for closure pours to occur at both bridges, bridge median barrier to get completed and restoration of the temporary median crossovers installed in Stage 1. Traffic willthen be placed into itsfinal configuration, allowing for the final lift of asphalt paving to occur utilizing night lane closures. East 3rd Street Bridge East 3rd Street Bridge requires four stages for construction: Stage 1 The firstactivities to occur during Stage 1 are the early utilityrelocations and the temporary alignment construction. There are two groups of utilityrelocations during this stage. The first group of utility 24" relocations entail relocating the Mt. Vernon sanitary sewer line, the Westchester County sewer, a portion of the flood wall that goes underneath the temporary bridge and the fire hydrant at the southeast corner of Hutchinson Avenue and East 3rd Street in order to construct the approaches to the temporary bridge. The second group of utility relocations that begin in this stage entail relocating the Consolidated 12" Edison (ConEd) gas line and electrical lines in order to have relocation occur outside of the ConEd no-work windows for both electrical and gas. Relocating the gas line prior to the seasonal window is critical to avoid having to leave the line,and therefore the bridge, in itsexisting location untilthe seasonal window liftsin April. Occurring concurrently with the utility relocation is the construction of the temporary bridge approaches from Hutchinson Avenue and Carol Avenue to the temporary East 3rd Street Bridge location. Once construction of the temporary approaches reaches itsapproximate final elevation, construction of the temporary bridge will begin. The temporary bridge willbe constructed at the western approach and be launched to land at the eastern approach. The temporary bridge willbe constructed and launched in segments during a weekend closure of the HRP. Once the temporary bridge is in place, relocation of the remaining utilities on to the temporary bridge will occur. After completing the temporary bridge approaches and paving, traffic will be switched to the temporary alignment and the existing 3rd Street Bridge will be closed. Stage 2 Stage 2 begins with demolition of the existing bridge, including stone removal and asbestos abatement. Demolition can only occur once all utilities have been removed and traffic has been placed onto the 3 EECRUZ007400 FILED: NEW YORK COUNTY CLERK 10/28/2022 05:53 PM INDEX NO. 652321/2020 NYSCEF DOC. NO. 72 RECEIVED NYSCEF: 10/28/2022 D900036 - Three Bridges Replacement Region 8 / -wa BERUL- Update 17 temporary bridge. Demolition of the existing bridge will occur during weekend directional closures of the HRP. Removal of the existing East 3rd Street Bridge is the predecessor for work to begin along the HRP. Due to our ATC 2, work can begin prior to the removal of the existing structure, but ultimately we chose not to as itwould introduce additional staging along the HRP. Stage 3 Stage 3 can begin once traffic is on the temporary bridge and the existing bridge has been demolished. The proposed East 3rd Street Bridge will be constructed in a single phase using Accelerated Bridge Construction (ABC) methods. Once the bridge superstructure elements have been completed, the East 3rd Street Bridge roadway approaches and final relocations of the Verizon and Extenet utilitieswill be completed. With the final paving complete traffic will be switched to the new East 3rd Street Bridge. Staging for this site will use the southbound HRP Exit 10 ramp gore area, as well at the Wolfs Lane ramp area. Stage 4 Stage 4 starts once the East 3rd Street Bridge is complete and traffic is shifted to its final location. Removal of the temporary elements starts with the de-launching of the temporary superstructure, which will occur using a weekend closure of the HRP. Following the de-launch will be the removal of the temporary substructures, removal of the approaches, and the final grading of the site. Hutchinson River Parkway (HRP) Hutchinson River Parkway (HRP) will be constructed in four stages and will begin after Stage 2 of East 3rd Street Bridge sequencing. Stage 1 Stage 1 begins behind temporary barrier along the southbound shoulder of HRP with the scopes of 20" relocation of the Westchester County Sanitary line, relocation of the Hutchinson River, installation of the ATC 2 and installation of the storm drainage trunk line.Once the trunk line is non- floodwall, installed, peak hour lane closures will be used to install the drainage crossings. Lanes will be returned to their existing capacity during peak hours. Material will be stored behind barrier along the river and at the southbound HRP Exit 10 ramp gore. Stage 2 The next stage of HRP construction, Stage 2, is focused on construction of the median of the proposed HRP. Work begins in this stage when drainage and paving of the southbound shoulder is complete and can accommodate traffic to be relocated to it.Work in this stage includes demolition of the existing median, installation of the median drainage system and median barrier construction. Once the median barrier has been completed, milling and paving of the southbound roadway will commence under off-peak hour lane closures. Installation of the drainage laterals crossing the northbound roadway occur in this stage under off-peak hour lane closures. Stage 3 Stage 3 moves to the northbound lanes of HRP. Work in this stage includes the drainage trunk line, northbound shoulder and acceleration lane including curbs, underdrain, pavement and guard railing. These activities are expected to occur during typical construction hours. Once the shoulder curb has been completed, milling and paving of the northbound roadway will commence under off-peak hour lane closures. 4 EECRUZ007401 FILED: NEW YORK COUNTY CLERK 10/28/2022 05:53 PM INDEX NO. 652321/2020 NYSCEF DOC.
