Project Description:

The existing Hopkins Covered Bridge, built in 1875, provides access to a single dwelling on a dead-end road. Years of neglect had led to significant deterioration of the structure, to the extent that a bypass bridge was installed in 1993.

The assignment involved the in-depth evaluation of the 91-foot long bridge and preparation of contract plans for a major rehabilitation. The goal was to restore the capacity of the bridge so that it could safely support 20-ton vehicle loading.

Many of the members of the Town Lattice trusses had to be replaced. Sawn Southern Pine timber was used. The floor system was also replaced and had to resort to glue-laminated components to provide the desired 20-ton capacity. The sway bracing system was substantially improved.

Work was completed in 1998.
