FIGURE I - Ultimately, in order to fully address the capacity deficiencies along West Chester Pike (PA Route 3) and Newtown Street Road (PA Route 252), as well as the queuing between the signalized intersections of West Chester Pike (PA Route 3) with Newtown Street Road and Bishop Hollow Road/Clyde Lane, it is necessary to also ban the westbound left-turn movement at Bishop Hollow Road. In order to provide an alternate route for this movement, it is necessary to construct a loop road on the southwest corner of West Chester Pike (PA Route 3) and Newtown Street Road (PA Route 252). The loop road is shown to intersect West Chester Pike (PA Route 3) at Roe Lane and intersect Newtown Street Road (PA Route 252) at Reese Avenue; however, the exact location and alignment has not been determined, and at this time, only the concept of a loop road is offered for consideration. This loop road would also serve the banned northbound Newtown Street Road (PA Route 252) left-turn movement at West Chester Pike (PA Route 3), which would eliminate the need to permit the northbound left-turn movement at Newtown Street Road (PA Route 252)/Winding Way. This improvement scenario was not necessary for the 2007 analysis conditions. The following intersection improvements are recommended:

West Chester Pike (PA Route 3) and Bishop Hollow Road/Clyde Lane
• Ban the westbound West Chester Pike (PA Route 3) left-turn movement.
• Widen West Chester Pike (PA Route 3) to provide three through lanes in
each direction.
• 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.
West Chester Pike (PA Route 3) and Winding Way/Proposed Loop Road
• Install a traffic signal, as warranted based on existing traffic volumes.
• Allow the northbound left-turn movement from the proposed loop road
by providing dual left-turn lanes, which will also serve the northbound
Newtown Street Road (PA Route 252) left-turn movement at West
Chester Pike (PA Route 3).
• Widen West Chester Pike (PA Route 3) to provide three through lanes in
each direction.
• Provide a second West Chester Pike (PA Route 3) left-turn lane in both
the eastbound and westbound directions.
Benefits
• Eliminates the need for widening at Newtown Street Road (PA Route 252)/Winding
Way/Saint Albans Avenue to permit the northbound left-turn movement.
• Improves the capacity and levels of service at the West Chester Pike (PA Route
3)/Newtown Street Road (PA Route 252) intersection.
Challenges
• Acquiring right-of-way and property for the construction of two loop roads on the
southeast and southwest corners of West Chester Pike (PA Route 3) and Newtown
Street Road (PA Route 252). Again, the exact alignment and location of these loop
roads is subject to change; however, it is only the concept for these loop roads that
are offered for consideration as a benefit to traffic operations.
Opinion of Costs
• The order of magnitude preliminary opinion of cost is between $10 to $11 million,
which includes construction costs, but excludes engineering fees, utility relocation,
and right-of-way acquisition costs.
