                    Transportation Improvements  

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.
