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 Ramps. The project limits along US 322 extend from the interchange with Bethel Road to the I-95 interchange.
As part of the design process, multiple interchange configurations will be evaluated and will include alternatives that provide the 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 US 322 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. Surrounding intersection improvements will also be incorporated into the study.
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 improve upon existing ITS equipment along the I-95 corridor and approaching highways.
