REPAIR

RICHMOND, VA

PROJECT DETAILS

This project aimed to enhance the structural integrity and safety of the bridges in the Richmond District, ensuring minimal disruption to traffic while performing essential repairs. The project involved comprehensive repairs and maintenance of various bridges within the Richmond District. Key components of the work included traffic control installation, where single and multiple lane closures were implemented along with partial shutdowns of traffic on I-64 and I-95 on-ramps. This also involved rerouting traffic and managing controlled traffic slow-rolls.

Additionally, bridge jacking and blocking were performed to support bridge structures during repairs. Steel repairs encompassed the replacement of deteriorated or rusted sections of steel girders, incorporating both full and partial penetration welds that underwent 100% X-ray testing to ensure integrity. Missing bolts on slip-critical joints were replaced, and critical components, such as end diaphragms, intermediate diaphragms, sole plates, and bearing plates, were also replaced.

Concrete rehabilitation involved repairing approach slabs, wingwalls, abutments, and deck slabs, which included reconstructing bridge bearing seats and performing crack injection for cracked concrete and gaps. Various tests, such as ultrasonic testing (UT), dye penetrant testing, magnetic particle testing, and X-ray inspections, were conducted to ensure quality and safety.

Furthermore, a carrier beam was designed and installed, leading to the overnight replacement of a bridge steel girder on I-95 Southbound. Emergency repairs included heat straightening of multiple bridge steel girders at various locations due to impacts from taller vehicles.
