The Pennsylvania Department of Transportation (PennDOT) invites the public to view and offer comment on the plans display for the project to improve the intersection of Route 3 (West Chester Pike) and I-476 in Marple and Haverford Townships in Delaware County.

The project involves improvements to the existing Route 3 (West Chester Pike) Interchange with Interstate 476.  The proposed improvements include the delineation/separation of the westbound Route 3 (West Chester Pike) off-ramp to the northbound I-476 on-ramp from the signalized intersection at South Lawrence Road.  The lane will no longer be controlled by the traffic signal and will be free-flowing.  The northbound I-476 on-ramp will be restriped and signed to carry two lanes up to the existing ramp meter.  South Lawrence Road will maintain the same lane configuration including dual left-turn lanes and a right-turn only lane.  A new channelized right-turn lane will be constructed at the intersection of Route 3 (West Chester Pike) & northbound I-476 off-ramp/on-ramp to accommodate vehicles from South Lawrence Road to northbound I-476.

A new cantilever overhead lane designation sign structure will be installed along westbound West Chester Pike in the grass median, east of North Lawrence Road.  There are no anticipated temporary or permanent right-of-way acquisitions for this project.  The existing traffic signals at the northbound I-476 off-ramp/on-ramp, South Lawrence Road and North Lawrence Road will be modified as necessary.  The ADA curb ramp and pedestrian facilities along the corridor will be evaluated and updated, as necessary, to meet current ADA standards.

The project is located at the boundary between Haverford and Marple townships within Delaware County.  The surrounding land use is primarily commercial along Route 3 (West Chester Pike) with some forested undeveloped land surrounding Darby Creek that crosses under Route 3 (West Chester Pike) and parallels I-476 within the corridor.
