Achievements & Awards

Replacement of Cranbury Road (Bridge No. 762.1) over Bear Brook, West Windsor, Mercer County, New Jersey

On March 13, 2019, the American Council of Engineering Companies [ACEC] presented the County of Mercer with the award of "Project of the Year" for the replacement of Cranbury Road Bridge No. 762.1.  This was the second award received for this project.  Johnson, Mirmiran & Thompson [JMT] provided engineering design services for the replacement of Cranbury Road Bridge over Bear Brook.  The existing four-span bridge, a simply supported adjacent pre-stressed concrete voided slab beam structure, was classified as structurally deficient due to the poor condition of the substructure, as well as functionally obsolete due to inadequate deck geometry.

JMT designed a two-span continuous curved steel plate girder bridge supported by the full height abutments and hammerhead pier founded on steel H-Pile foundation.  The brown color open steel four-bar bridge railings was designed to provide drivers and pedestrians a view of the scenic area.
