Project Overview

Role: Prime Consultant

M&J Engineering (M&J) provided construction inspection services for the replacement of Bridge No. 04069, which had been classified as structurally deficient. Originally built in 1936 and reconstructed in 1993, the structure featured a reinforced concrete deck and steel beam superstructure, supported by stone masonry abutments and wingwalls. The bridge measured 40 feet in length and 24.8 feet in width, with a roadway width of 23.4 feet and an approach width of 18 feet. It accommodated two lanes of vehicular traffic (one lane in each direction) but lacked sidewalks.

The replacement of Bridge No. 04069 included a micro pile foundation, cast-in-place substructure, new structural steel, cast-in-place deck, full road reconstruction, and utility relocation. The work for this bridge was completed in multiple stages. During the first stage, the road was closed, and a full detour was implemented. There were many environmental concerns due to the bridge’s location over freshwater. Once new south-side wingwalls were constructed, the water main was relocated to the south side of the bridge, and a dedicated beam was installed to secure the new connection to the bridge. During the next stage, the remainder of the bridge was demolished, and new footings, abutments, deck, and approach slabs were installed. To finalize the project, new pavement, deck joints, guard rails, fencing, and striping were completed.
