Replacement of Sunnyside Avenue Bridge over Indian Creek
Located in a wetland, Sunnyside Avenue Bridge was a 37-ft span steel beam bridge¡ªit, and the adjacent roadway, were flooding frequently and needed to close to traffic whenever this happened. As a frequently travelled route, shutting down the road resulted in severe traffic jams on local roads and inconvenience to the public.
As a trusted consultant and partner of the Prince George¡¯s County Department of Public Works and Transportation, at the County¡¯s request, our design team provided preliminary studies, concept development, environmental documentation, final design for the replacement of the existing single span bridge. The new bridge is a seven-span continuous adjacent box beam supported on steel pile bents and semi-integral abutments. The bridge carries two 12-foot lanes, two bike paths, two shoulders, and two sidewalks. For storm water management, two submerged gravel wetlands were installed due to the existence of a high water table, poor draining soils and natural wetlands. ?
The new bridge is a significantly larger bridge with much higher profile to pass the 25-year storm without increasing the 100-year flood elevation. With the new bridge now constructed, the road does not get overtopped by flooding and can remain open to traffic during annual heavy storms.??
