93445 | Route 1 Improvements - North (Section RC2) (Middletown Township & Bensalem Township, Bucks County)

The S.R. 0001 Group 03S Section RC2 project, located in Bensalem and Middletown Townships, Bucks County, PA, extends from a point just south of the Neshaminy Interchange to just south of S.R. 2045 (Old Lincoln Highway), a distance of 1.5 miles. The project encompasses reconstruction and widening of S.R. 0001, including: upgrading 2 interchanges S.R. 8055 (Neshaminy) and S.R. 8067 (Penndel); and reconstruction of 3 bridges. The improvements for this section of S.R. 0001 are as follows:
-Widening of US 1 median width to meet current design criteria.
-The height of the bridge carrying US 1 over Rockhill Drive has been increased to accommodate the required 14’-6” vertical clearance between the bottom of the new bridge beams and the proposed elevation of Rockhill Drive below. The roadway along SR 0001 has been raised to meet the new bridge elevation.
-Adding a third travel lane along US 1 in each direction from just south of the Neshaminy interchange north to the Penndel interchange.
-Adding an auxiliary lane along US 1 in both the northbound and southbound directions between the PA Turnpike interchange and Neshaminy interchange.
-Reconfiguring the Neshaminy interchange to relocate the ramp from Rockhill Drive to US 1 northbound from the northeastern quadrant of the interchange to the southeastern quadrant as a loop ramp, eliminating the left turn movement immediately west of the existing Neshaminy Mall traffic signal, and improving the geometry of the interchange ramps, where feasible.
-Modifications to both existing signalized intersections on Rockhill Drive to improve traffic flow into and out of the Neshaminy Mall and the Horizon Corporate Center.
-North of the Neshaminy interchange, adding/lengthening auxiliary (acceleration and deceleration) lanes along US 1 in both the northbound and southbound directions for ramps to and from Rockhill Drive.
-Structure improvements, including the replacement of three existing bridges, the construction of five retaining walls, and construction of one noise wall. The existing bridges to be replaced are those that carry US 1 over Rockhill Drive, Neshaminy Creek, and US 1 Business and the CSX and SEPTA rail lines.
-US 1 southbound will be realigned across Neshaminy Creek to allow traffic to be maintained on the existing bridge during construction of the proposed structure on new alignment.
-Sidewalks, ADA ramps, and pedestrian signals were installed along Rockhill Drive within the project limits. The existing bus stops along Rockhill Drive were relocated to accommodate the widening of the roadway. All bus stops are in similar locations to those prior to construction.
-Guiderail upgrades, drainage improvements, and signage improvements.
Project CMP (Congestion Management Process) commitments include signal improvements, sidewalks and other improvements for pedestrians, investigation of new bus stops and enhanced bus services in consultation with SEPTA, safety improvements including increased speed enforcement, and outreach to employers to promote transportation demand management strategies. See DVRPC’s 2013-2014 memorandum on supplemental strategies for details related to this project.
