West Chester Pike (PA Route 3)/Newtown Street Road (PA Route 252) and Immediate Intersections

Figure A - At the intersection of West Chester Pike (PA Route 3)/Newtown Street Road (PA Route 252), ban the eastbound West Chester Pike (PA Route 3) left-turn movement, and divert this traffic to Winding Way. The following intersection improvements are recommended:
West Chester Pike (PA Route 3) and Newtown Street Road (PA Route 252)
• Ban the eastbound West Chester Road (PA Route 3) left-turn movement.
• Widen West Chester Pike (PA Route 3) to provide three through lanes in
each direction.
• Lengthen the second through lane in the northbound and southbound
directions along Newtown Street Road (PA Route 252) south of West
Chester Pike (PA Route 3).
• Modify the traffic signal phasing/timing plan.

West Chester Pike (PA Route 3) and Bishop Hollow Road/Clyde Lane
• Widen West Chester Pike (PA Route 3) to provide three through lanes in
each direction.
• Modify the traffic signal phasing/timing plan.

West Chester Pike (PA Route 3) and Winding Way/Roe Lane
• Install a traffic signal, as warranted based on existing traffic volumes.
The Winding Way exiting left-turn movement is prohibited at this
intersection, and although PENNDOT does not typically approve a traffic
signal based on right-turning side-street traffic volumes, due to the high
volume of right-turning vehicles exiting Winding Way, the high volume
of left-turn vehicles entering Winding Way, and the high traffic volumes
along West Chester Pike (PA Route 3), a traffic signal is recommended.
Newtown Street Road (PA Route 252) and Winding Way/Saint Albans Avenue
• Provide a second southbound Newtown Street Road (PA Route 252) left-
turn lane.
• Provide a second eastbound Winding Way left-turn lane.
•    Modify the traffic signal phasing/timing plan.
Benefits
• Traffic flow along West Chester Pike (PA Route 3) will be greatly improved.
• Improved intersection capacity for the West Chester Pike (PA Route 3) eastbound
and westbound approaches at Newtown Street Road (PA Route 252).
Challenges
• Although improved, there will be traffic congestion along Newtown Street Road (PA
Route 252) at the intersection with West Chester Pike (PA Route 3). In order to
improve the Newtown Street Road (PA Route 252) approaches, second northbound
and southbound Newtown Street Road (PA Route 252) left-turn lanes are required,
which would likely require additional right-of-way (see bubble inset on Figure A).
• Widening is needed along West Chester Pike (PA Route 3) to provide three through
lanes in each direction.
Opinion of Costs
• The order of magnitude preliminary opinion of cost is between $4 to $5 million,
which includes construction costs, but excludes engineering fees, utility relocation,
and right-of-way acquisition costs.

Figure B - At the intersection of West Chester Pike (PA Route 3)/Newtown Street Road (PA Route 252), ban all left-turn movements. The eastbound West Chester Pike (PA Route 3) left-turn movement will continue to divert to Winding Way, as shown in Figure A. The northbound Newtown Street Road (PA Route 252) left-turn movement will travel through the intersection with West Chester Pike (PA Route 3), turn left onto Winding Way by permitting this currently banned movement and access West Chester Pike (PA Route 3) via Winding Way. The southbound Newtown Street Road (PA Route 252) left-turn movement will travel through the intersection with West Chester Pike (PA Route 3), turn left onto a new loop road on the southeast corner of the intersection, and access West Chester Pike (PA Route 3) opposite Bryn Mawr Avenue. The westbound left-turn movement will turn left at a new loop road opposite Bryn Mawr Avenue, and access Newtown Street Road (PA Route 252) via a new loop road intersection. The following intersection improvements are recommended:

West Chester Pike (PA Route 3) and Newtown Street Road (PA Route 252)
• Ban all left-turn movements.
• Lengthen the second through lane in the northbound and southbound
directions along Newtown Street Road (PA Route 252) south of West
Chester Pike (PA Route 3).
• Modify the traffic signal phasing/timing plan.

West Chester Pike (PA Route 3) and Bishop Hollow Road
• Close the southbound Clyde Lane approach and relocate it to the west as
a separate T-intersection.

lane.
• Provide a separate northbound Bishop Hollow Road left-turn lane.
• Modify the traffic signal phasing/timing plan.

West Chester Pike (PA Route 3) and Relocated Clyde Lane
• Close the southbound Clyde Lane approach at Bishop Hollow Road and
relocate it to the west as a separate T-intersection.
• Install a traffic signal, as warranted, based on existing traffic volumes.
• Provide a separate eastbound West Chester Pike (PA Route 3) left-turn
lane.
• Provide separate southbound Clyde Lane left- and right-turn lanes.
West Chester Pike (PA Route 3) and Winding Way/Roe Lane
• Install a traffic signal, as warranted, based on existing traffic volumes.

Newtown Street Road (PA Route 252) and Winding Way/Saint Albans Avenue
Option 1
• Permit the northbound Newtown Street Road (PA Route 252) left-
turn movement (currently prohibited) by providing dual left-turn
lanes in order to accommodate the banned northbound left-turn
movement from West Chester Pike (PA Route 3)/Newtown Street
Road (PA Route 252).
• Provide a second southbound Newtown Street Road (PA Route
252) left-turn lane.
• Provide a second eastbound Winding Way left-turn lane.
• Provide a separate eastbound Winding Way right-turn lane.
• Modify the traffic signal phasing/timing plan.
Option 2
• Provide a second access along Newtown Street Road (PA Route
252) north of Winding Way to serve the proposed SAP America
expansion, the occupancy of the Lyondell space, Ellis Preserve,
and Town Center development, as well as some regional traffic, to
preserve the function of Winding Way as an alternate route to the
West Chester Pike (PA Route 3)/Newtown Street Road (PA Route
252) intersection.
• Permit the northbound Newtown Street Road (PA Route 252) left-
turn movement (currently prohibited) by providing a separate
single left-turn lane in order to accommodate the banned
northbound left-turn movement from West Chester Pike (PA
Route 3)/Newtown Street Road (PA Route 252).
• Provide a second southbound Newtown Street Road (PA Route
252) left-turn lane.
• Provide a second eastbound Winding Way left-turn lane.
• Provide a separate eastbound Winding Way right-turn lane.
• Modify the traffic signal phasing/timing plan.

Newtown Street Road (PA Route 252) and Proposed Loop Road
• Construct a loop road from Newtown Street Road (PA Route 252)
opposite Reese Avenue (or another similar location) to West Chester Pike
(PA Route 3) opposite Bryn Mawr Avenue via the Dunwoody Village
access.
• Install a traffic signal, as warranted, based on the future projected traffic
volumes.
• Widen Newtown Street Road (PA Route 252) to provide a second through
lane in each direction.
• Provide a separate northbound and southbound Newtown Street Road
(PA Route 252) left-turn lane.

West Chester Pike (PA Route 3) and Bryn Mawr Avenue/Dunwoody Village Access/Proposed Loop Road
• Construct a loop road from Newtown Street Road (PA Route 252) to West
Chester Pike (PA Route 3) opposite Bryn Mawr Avenue via the
Dunwoody Village access.
• Provide a separate northbound Dunwoody Village access/proposed loop
road right-turn lane.
• Modify the traffic signal phasing/timing plan.
Benefits
• Improved intersection capacity and levels of service at West Chester Pike (PA Route
3) and Newtown Street Road (PA Route 252) on all approaches.
• Does not require widening for additional through lanes along West Chester Pike (PA
Route 3) or turning lanes at the constrained intersection of West Chester Pike (PA
Route 3) and Newtown Street Road (PA Route 252) in order to achieve acceptable
levels of service.
• With the relocation of Clyde Lane, and greater intersection spacing, vehicular queues
are reduced along West Chester Pike between the intersections with Bishop Hollow
Road and Newtown Street Road (PA Route 252), and better levels of service are
achieved as two separate T-intersection.
Challenges
• Acquiring right-of-way and property for the construction of a loop road on the
southeast corner of West Chester Pike (PA Route 3) and Newtown Street Road (PA
Route 252). The exact alignment and location of this loop road is subject to change;
however, it is only the concept for a loop road on this corner that is offered for
consideration as a benefit to traffic operations.
• By banning the northbound Newtown Street Road (PA Route 252) left-turn
movement at West Chester Pike (PA Route 3), significant widening is needed to
accommodate the additional traffic volumes at the intersection of Newtown Street
Road (PA Route 252) and Winding Way/Saint Albans Avenue.
• With relocation of Clyde Lane to provide a new signalized T-intersection, the traffic
signal spacing is very close along West Chester Pike (PA Route 3).
Opinion of Costs
• The order of magnitude preliminary opinion of cost is between $4 to $5 million or
between $4.5 to $5.5 million with Option 1 or Option 2, respectively, at Newtown
Street Road (PA Route 252)/Winding Way/Saint Albans Road, which includes
construction costs, but excludes engineering fees, utility relocation, and right-of-way
acquisition costs.

Figure C - Additional intersection configurations were evaluated for West Chester Pike (PA Route 3) and Bishop Hollow Road/Clyde Lane. Instead of closing Clyde Lane and creating a new signalized T-intersection to the west along West Chester Pike (PA Route 3), as shown in Figure B, another option is to close Clyde Lane at its present intersection with West Chester Pike (PA Route 3), and divert the southbound Clyde Lane traffic to Winding Way/Roe Lane. The following intersection improvements are recommended:
West Chester Pike (PA Route 3) and Bishop Hollow Road
• Close the southbound Clyde Lane approach and divert traffic to Winding
Way.
• Provide a separate eastbound West Chester Pike (PA Route 3) right-turn
lane.
• Provide a separate northbound Bishop Hollow Road left-turn lane.
• Modify the traffic signal phasing/timing plan.

West Chester Pike (PA Route 3) and Winding Way/Roe Lane
• Install a traffic signal, as warranted based on existing traffic volumes.
• Allow the southbound left-turn movement from Winding Way by
providing a separate left-turn lane.
• Provide a second southbound Winding Way right-turn lane.
Benefits
• As compared to Figure B, the need for an additional traffic signal is eliminated.
• With the elimination of Clyde Lane, vehicular queues are reduced along West
Chester Pike between the intersections with Bishop Hollow Road and Newtown
Street Road (PA Route 252).
Challenges
• Although the vehicular queues are reduced between Bishop Hollow Road and
Newtown Street Road (PA Route 252), the two signalized intersections continue to
be closely spaced.
Opinion of Costs
• The order of magnitude preliminary opinion of cost is between $4 to $5 million,
which includes construction costs, but excludes engineering fees, utility relocation,
and right-of-way acquisition costs.

Figure D - Additional intersection configurations were evaluated for West Chester Pike (PA Route 3) and Bishop Hollow Road/Clyde Lane. This option recommends shifting the intersection to the west along West Chester Pike (PA Route 3) in order to provide better spacing with the signalized intersection of West Chester Pike (PA Route 3) and Newtown Street Road. The following intersection improvements are recommended:

West Chester Pike (PA Route 3) and Bishop Hollow Road/Clyde Lane
• Relocate both the Bishop Hollow Road and Clyde Lane approaches to the
west along West Chester Pike (PA Route 3).
• Provide separate northbound Bishop Hollow Road and southbound
Clyde Lane left-turn lanes.
• Provide a separate northbound Bishop Hollow Road right-turn lane.
• Modify the traffic signal phasing/timing plan.
Benefits
• Traffic signal spacing along West Chester Pike (PA Route 3) can be maximized
between Winding Way and Newtown Street Road (PA Route 252) in order to
manage the vehicular queues.
Challenges
• Acquiring property to shift the Bishop Hollow Road approach to West Chester Pike
(PA Route 3) to the west within the existing dense residential development located
in the area.
Opinion of Costs
• The order of magnitude preliminary opinion of cost is between $4 to $5 million,
which includes construction costs, but excludes engineering fees, utility relocation,
and right-of-way acquisition costs.
