Nobis is part of the Design-Build team to provide geotechnical engineering and hydrology/hydraulic services for replacement of the 2-lane and 423 feet long Derek S. Hines Memorial Bridge, a four-span existing structure over the Merrimack River. The current structure consists of two approach spans supported on stone masonry abutments at one end and rest piers on the other end, on which the 156 feet long swing span, pivoted on the center pier in the middle of the bridge rests.
