15477 | I-95/322/Conchester Hwy. Interchange/Impvts. (322) (Upper Chichester Township, Chester City & Chester Township, Delaware County)

The SR 95, Section 322 project entails the reconfiguration of the interchange connecting two heavily traveled corridors, I-95 and US 322. The I-95 / US 322 interchange, constructed in the late 1960's, employs poor geometry that includes a left-lane on-ramp requiring a major weave across three high volume lanes of traffic. Limited sight distances, minimal acceleration and deceleration ramp lengths, and roadway segments without shoulders compound the fundamental design problems. Consequently, this area has been recognized as a Physical Highway Bottleneck under the FHWA's Significant Traffic Bottleneck Initiative. There are five existing bridges associated with the interchange: I-95 Southbound over US 322 and Ramp A; I-95 Northbound over Ramp A; Ramp N over US 322 and Ramp A; Highland Avenue over I-95 and Engle Street over I-95. The project will involve the replacement of these structures. Other structures in the project vicinity include culverts carrying waterways under I-95. The project limits along I-95 extend from just south of the US 322 interchange to the Commodore Barry Bridge Off Ramp. The US 322 bridge over CSXT, has been broken out to a separate MPMS#104343, and will be funded under the DVRPC TIP. The project limits along US 322 extend from the interchange with Bethel Road to the I-95 interchange. A point of access study will be prepared which will include an evaluation of providing two direct movements that currently are not provided at the interchange: I-95 NB to US 322 WB and US 322 EB to I- 95 SB.

Alternatives for the interchange will include providing additional auxiliary lanes on I-95 between Highland Avenue and the Commodore Barry Bridge ramps at I-95. I-95 SB may include the existing three through lanes plus an additional fourth auxiliary lane between ramps. I-95 NB may include the existing three through lanes, the existing auxiliary lane and an additional auxiliary lane. Local roadway improvements are also anticipated for Township Line Road. This section of I-95 has ITS equipment and is a crucial link in PennDOT's Traffic and Incident Management System (TIMS) Program. This project will maintain and improvement upon existing ITS equipment along the I-95 corridor and approaching highways.
This project is integral to the Delaware Valley Freight Corridors Initiative.
