Underside of BR 1-501 including piers in the Christina River
The pile caps of Piers 2 and 3 which are located in the Christina River have been under-mined by scour leaving portions of the steel H-piles exposed. Some portions of the steel H-piles also exhibit corrosion. Several expansion bearings are not functioning due to age and condition. Some portions of the steel tub girders are showing signs of fatigue and are in need of strengthening.
This project involves the rehabilitation of BR 1-501 substructure. At Piers 2 and 3 which are located in the Christiana River, the work includes installing concrete pile jackets over the steel H-piles and installing rip rap scour protection. In addition, the entire line of expansion bearing on Piers 6, 14, and 15 will be replaced. Steel retro-fit of tub girders will be installed over pier and abutment supports.
Design work to be completed no later than Spring 2018.
Construction work to be completed Fall of 2020.
