About the Project

Oak Street Bridge is located over Tripps Run, between S. Lee Street and Timber Lane. 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. Watch the Planning Commission meeting from October 2019 when the conceptual design was discussed (download presentation).

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 cracks with some exposed rebar.

The bridge has been on a yearly inspection cycle since 2012. The rating has not changed and there have been no major changes from the 2012 condition. Each annual inspection recommends replacing or repairing the steel beams and concrete deck immediately. Draft Concept
