King of Prussia, PA – The Pennsylvania Department of Transportation (PennDOT) announced today that construction activities will take place on northbound Interstate 476 at the MacDade Boulevard Interchange in Ridley Township, Delaware County, under a project to improve travel and safety on MacDade Boulevard and at the northbound I-476 and MacDade Boulevard Interchange.

Motorists are advised of the following travel restriction:

• Monday, June 5, through Friday, June 9, from 8:00 PM to 5:00 AM the following morning, alternating lane closures are scheduled on northbound I-476 at the MacDade Boulevard Interchange for milling and paving; and
• Thursday, June 8, and Friday, June 9, from 9:00 PM to 5:00 AM the following morning, the northbound I-476 ramp to westbound MacDade Boulevard will be closed for bridge beam erection. During the closure, motorists will be directed to use the northbound I-476 ramp to eastbound MacDade Boulevard, Fairview Road, and Route 320 (Chester Road).

Motorists are advised to allow extra time when traveling near the work area because backups and delays will occur. All scheduled activities are weather dependent.

Under this contract, PennDOT's contractor will construct a left turn lane on eastbound MacDade Boulevard at the Bullens Lane Intersection to help reduce potential rear-end crashes and improve sight lines for left turning vehicles. Traffic signals will also be modernized, and updated curb ramps will be installed at each quadrant of the intersection to meet current Americans with Disability Act (ADA) requirements.

In addition, two dynamic message boards will be mounted on steel columns, as well as CCTV cameras installed on traffic signals along MacDade Boulevard between Bullens Lane and Fairview Road to improve connectivity.

The project plan also involves improving the ramp from northbound I-476 to MacDade Boulevard by widening and realigning the westbound ramp where it approaches MacDade Boulevard to form a "T" intersection, where drivers will turn left or right onto MacDade Boulevard at a newly signalized intersection. 

To help relieve traffic congestion, auxiliary lanes will be constructed on northbound I-476 within the existing roadway footprint just north of the MacDade Boulevard Interchange and just south of the U.S. 1 Interchange. Guiderail installations are also planned along sections of northbound I-476.

The existing pedestrian bridge over Crum Creek will also be removed and a new pedestrian bridge will be reconstructed with a new alignment adjacent to MacDade Boulevard.

Allan Myers, LP, of Worcester, Montgomery County, is the general contractor on the $16.2 million project, which is financed with 80% federal funds and 20% state funds. The entire project is scheduled to finish in summer 2026.
