bridge on james street

This is a bridge replacement project that entails the construction of a new 393’-11 7/8”, 5-span bridge on James Street over Christina River in New Castle County, Delaware.
The existing bridge BR 1-159 is structurally deficient, with its movable portion inoperable. Its steel superstructure exhibits heavy corrosion and section loss.
The new bridge structure is being constructed just east of the existing bridge alignment. It is 393’-11 7/8” long with 5 spans. The span lengths vary from 55’-5 1/2” (Span 5) to 88-1 1/8” (Span 2). The structure has a curb-to-curb width of 28 feet and a 10-foot wide bike and pedestrian way. The out-to-out width of 42’- 5 ½” consists of two 12-foot lanes, two 2-foot shoulders, two 1’-8 1/4” parapets and 1’-1” for a handrail. The deck elevation at the centerline is 12.76 feet at Abutment A and 12.5 feet at Abutment B. The maximum embankment height is approximately 9 feet at Abutment A and 5.5 feet at Abutment B.
Rite Geosystems Inc., our USA Company was entrusted to provide complete instrumentation for the project.
Scope of works include:
1. Supply of geotechnical instruments
