This project involved performing major preventive Bridge maintenance & Repair for three (3) bridges at the Glebe Road Interchange on I-395 in Alexandria, VA. Main scope of the work for these three projects as follows:
Deck Repair, deck milling and LMC-VE overlay.
Painting superstructure steel and bearings.
Deck joint elimination and / or deck joint reconstruction.
Evaluate bearing replacement as required for joint elimination.
Substructure Concrete delamination / spall and crack repair.
Application of waterproofing to sub structure
Work includes saw cut and demo of existing bridge deck, Type A and B patching, installation of joint sealant and expansion dams. This work had to be performed without impeding existing traffic and therefore involved extensive maintenance of traffic (MOT) coordination and implementation through lane closures during non-peak hours of traffic on this heavily travelled corridor of I-395.
