Oak Street Bridge is located over Tripps Run, between S Lee St and Timber Ln. The scope of the work is the replacement of steel beams and concrete deck. Ancillary benefits of the project are improving pedestrian accessibility and trail access point to Howard E. Herman Stream Valley Park.
Oak Street Bridge is a simple span steel beam bridge with reinforced concrete deck and concrete abutments. In 2012, Dewberry inspectors found the bridge to be in poor condition with a bridge rating of 4 out of 10. There is severe corrosion in the steel beam webs. Timber blocking was installed at locations where steel beam webs were severely corroded. Concrete deck has spalling and numerous hairline cracking with some exposed rebar. The bridge is on a yearly inspection cycle and was inspected from 2012 through 2016. The rating has not changed and there have been no major changes from the 2012 condition. All inspections recommend replacing or repairing the steel beams and concrete deck immediately.
The estimated cost for planning, design, and construction is $750,000 to $1,000,000. This project is funded through Regional Surface Transportation Program (RSTP) funds and administered by the Virginia Department of Transportation (VDOT).
