The Rehabilitation of Bridges 1 & 1A on Rising Sun Lane over Brandywine Creek . New Castle County, Delaware.
Bridge 1-001A is a stone arch just south of the Brandywine Creek on Rising Sun Lane and was ranked No. 1 on the list of DelDOT’s structurally deficient bridges due to the advanced deterioration of the mortar in the arch and spring walls. Bridge 1-001 is the steel Pratt through truss over the Brandywine Creek, and was ranked No. 7 due to years of advancing deterioration and concern over overstress in the deteriorated members and weakening of fatigue sensitive details. Bridge 1 is the last remaining truss of it’s kind in Delaware. The route is a vital link for the community, and the team was committed to completing the necessary repairs to reduce future maintenance and ensure the public’s safety as expeditiously as possible. The rehabilitation and reuse of these historic resources help with preservation of the history of Delaware.
