BR 111 on N253 Benge Road over Red Clay Creek

Description – This project involves the rehabilitation of Bridge 111. The work includes replacing the existing concrete deck with a new concrete deck and barriers, minor repairs of the substructure, and minor approach roadway work.

Justification – Deterioration of the existing concrete deck has caused the bridge to become structurally deficient. The bridge was selected by the Pontis Bridge Management System for work. Rehabilitation of this bridge will help DelDOT meet its performance measure for percentage of bridges in poor condition.

 BR 148A&B on N330 Greenbank Road over Red Clay Creek

Description – This project involves the rehabilitation of Bridges 148A&B. The work includes replacing the existing concrete deck with a new concrete deck and barriers, minor repairs of the substructure, cleaning and painting the existing steel members, and minor approach roadway work. Additional work includes lining Bridge 148B.

Justification – Deterioration of the existing concrete deck of Bridge 148A has caused the bridge to become structurally deficient. Bridge 148B is a corrugated metal pipe with significant corrosion and 100% section loss at the waterline at several locations along the pipe. The bridges were selected by the Pontis Bridge Management System for work. Rehabilitation of these bridges will help DelDOT meet its performance measure for percentage of bridges in poor condition.

 BR 251 on N355 Harmony Road over White Clay Creek

Description – This project involves the rehabilitation of Bridge 251. The work includes replacing the existing concrete deck with a new concrete deck and barriers, minor repairs of the substructure, and minor approach roadway work.

Justification – Deterioration of the existing concrete deck has caused the bridge to become structurally deficient. The bridge was selected by the Pontis Bridge Management System for work. Rehabilitation of this bridge will help DelDOT meet its performance measure for percentage of bridges in poor condition.

 BR 308 on N378 Clarks Corner Road over Dragon Run

Description – This project involves the replacement of Bridge 308. The work includes replacing the existing concrete box beam bridge with a new bridge consisting of concrete box beams with a concrete deck. Additional work includes placing riprap in the stream for scour protection, installation of guardrail, and reconstruction of the approach roadway as needed.

Justification – The top of the fascia box beam has deteriorated along the gutter line to the point where a hole has formed. This deterioration has caused the bridge to become structurally deficient. The bridge was selected by the Pontis Bridge Management System for work. Replacement of this bridge will help DelDOT meet its performance measure for percentage of bridges in poor condition.

 BR 634 on SR100 DuPont Road over Delaware Valley RR

Description – This project involves the rehabilitation of Bridge 634. The scope of work includes replacement of the concrete deck with a new concrete deck and barriers, cleaning and greasing of the bearings, cleaning and painting of steel members, and repair of cracks and spalls in the concrete piers and abutments. Additional work includes minor approach roadway reconstruction and installation of guardrail as needed.

Justification – Deterioration of the existing concrete deck has caused the bridge to become structurally deficient. Cleaning and painting the steel girders will lengthen the life of the superstructure. The bridge was selected by the Pontis Bridge Management System for work. Rehabilitation of this bridge will help DelDOT meet its performance measure for percentage of bridges in poor condition.

BR 714 on N347 Chapman Road over I-95

Description – This project involves the rehabilitation of Bridge 714. The scope of work includes replacement of the concrete deck with a new concrete deck and barriers, cleaning and greasing of the bearings, cleaning and painting of steel members, repair of cracks and spalls in the concrete piers and abutments.

Justification – Deterioration of the existing concrete deck has caused the bridge to become structurally deficient. There are also spalls and delaminations on the piers and abutments that need to be repaired. Cleaning and painting the steel girders will lengthen the life of the superstructure. The bridge was selected by the Pontis Bridge Management System for work. Rehabilitation of this bridge will help DelDOT meet its performance measures for percentage of bridges in poor condition and the percentage of structurally deficient bridges by deck area on the NHS.

BR 717 on I-95 NB over SR1

Description – This project involves the rehabilitation of Bridge 717. The scope of work includes replacement of the concrete deck with a new concrete deck and barriers and minor repair of cracks and spalls in the concrete substructure.

Justification – Deterioration of the existing concrete deck has caused the bridge to become structurally deficient. The bridge was selected by the Pontis Bridge Management System for work. It was ranked 76th on the 2013 DelDOT Bridge Deficiency List. Rehabilitation of this bridge will help DelDOT meet its performance measures for percentage of bridges in poor condition and the percentage of structurally deficient bridges by deck area on the NHS.

 BR 759 on I-95 over Brandywine River

Description – This project involves the rehabilitation of Bridge 759. The scope of work includes replacement of the concrete deck with a new concrete deck and barriers, replacement of the steel fascia girders, replacement of some of the steel diaphragms, cleaning and greasing of the bearings, painting of steel members, repair of cracks and spalls in the concrete piers and abutments.

Justification – The emergency closure of I-495 has accelerated the deterioration of the existing bridge deck. There are also spalls and delaminations on the piers and abutments that need to be repaired. The fascia girders have many fatigue cracks and require replacement. The bridge was selected by the Pontis Bridge Management System for work. Rehabilitation of this bridge will help DelDOT meet its performance measures for percentage of bridges in poor condition and the percentage of structurally deficient bridges by deck area on the NHS.
