Nearly 1/3 of the Nation's bridges are structurally or functionally deficient. T&M's structural engineering staff is prepared to handle the task of repairing or replacing these deficient bridges and highway related structures. Members of the structural staff are highly experienced in the design of new bridges as well as the inspection, rehabilitation and widening of existing structures. This includes historic bridges, steel multi-girder, box girder, curved girder, trusses, timber bridges, prestressed and cast-in-place concrete structures, highway, railroad and pedestrian bridges, tunnels and culverts on major urban and toll expressways, state highways and local roadways.

T&M's staff has managed multiple bridge repair and upgrading programs for the NJ Highway Authority (NJHA), the NJ Turnpike Authority (NJTA), the NJ Department of Transportation (NJDOT), Delaware River Port Authority (DRPA), and has served numerous counties in NJ in the inspection/rehabilitation/replacement of their bridges.

In addition to the staff's vast bridge experience, T&M's structural engineering experience covers a wide spectrum of disciplines such as dam/spillway analysis and rehabilitation; historic structure restorations; toll plaza design, expansion and repairs; retaining walls and bulkhead design; coastal facility design; communication tower supports; and construction engineering such as temporary structures, temporary sheeting design, and many other unique structures.

Additionally, staff members have managed the inspection and restoration of several historic Delaware and Raritan Canal projects for the NJ Water Supply Authority, NJDOT and the City of New Brunswick.
Some representative bridge design and inspection projects include:

  • Fast track design of two bridges and five culverts for Route 33 Freeway Bypass in Freehold Township for the NJDOT
  • Bridge viaduct widening (440' long) over the Garden State Parkway (GSP) at Interchange 127 in Woodbridge for the NJHA
  • Replacement of bridges over Pews Creek and Comptons Creek in Port Monmouth for the County of Monmouth
  • Inspection of 160 bridges for the NJHA, and 37 Monmouth County bridges for the NJDOT
  • New two-span freight railroad bridge and two-span four-lane roadway bridge over Main Street, South Amboy and NJ Transit's electrified North Jersey Coast Line
  • Rehabilitation of the Pine Lake Dam, Manchester, NJ
  • Rehabilitation of the Skyline Lake Dam, Ringwood, NJ
  • Alternative bridge design for the Union County Light Rail Transit Line over the New Jersey Turnpike
  • Meadow Road over Route 1, West Windsor, NJ
  • T&M completed a design-build structural walkway and fishing pier for DRPA in South Camden, NJ
