FPA provided professional engineering design and construction support services for the replacement of a 100 year old stone arch bridge (known as NJDOT Structure No. 1809-153) which carries US 202 over the Mine Brook.  During the preliminary design phase, traffic demands of Route 202 were evaluated and the adjacent environmentally sensitive areas were identified.  The narrow width of the existing bridge precluded staged construction.  A fast-track construction approach with a short duration detour was the only option.

The proposed replacement structure consisted of precast concrete 3-sided culvert sections as well as precast concrete stub footings along with precast wingwalls.  Total duration of construction, from start of demolition to reopening the road was only six (6) weeks.

To complete the look of the original bridge, stone veneer from a local quarry was used on the exposed surfaces of the bridge to replicate the look of the original bridge and to maintain the historic character of the area.

This project was named 2009 Project of the Year by the American Society of Highway Engineers, and received an Honorable Mention at the 45th Annual ACI New Jersey Concrete Awards.
