Oldcastle Precast –Croydon, Pa., continues to supply specialty precast concrete pipe for the Milnor Street spur ramp’s stormwater drainage system which is a portion of Pennsylvania Department of Transportation’s (PennDot) $30 million-plus I-95 Revive project. The I-95 Revive project is a long-term, multi-phase infrastructure initiative to improve and rebuild the 51 miles of I-95 in Pennsylvania to meet the future transportation needs of the region and state.
A portion of the I-95 Revive project involves the widening and rebuilding of the existing northbound on-ramp to include a spur ramp from Milnor Street. The spur ramp is designed to reduce the volume of commercial traffic on State Road and other roads on the west side of I-95 by accommodating the heavy vehicles that serve businesses between I-95 and the river. In addition, improvements are being made to the Milnor Street spur ramp’s storm water drainage system.
Oldcastle Precast, contracted by Tony DePaul & Son, supplied custom engineered elliptical precast concrete pipe for the Milnor Street spur storm water drainage system. The use of heavy wall, 34- by 53-inch Type A/SH Shore Trench Box 30 foot by 1.5 foot, fill design pipe meets the challenge posed by the 30 feet of fill required at the ramp. With deep fills necessary in the ramp area, the precast concrete pipe had to be engineered to handle the weight load of 30 feet of fill compacted over the concrete pipe. The pipe had an outside diameter of 55-inches by80-inches weighing nearly 20,000 pounds each. The specialty precast concrete pipe is produced with a special concrete mix and added reinforcement to increase the strength and long-term performance for Penn-DOT.
Tony DePaul & Son out of Blue Bell, Pa, is the general contractor for the project.
