BOULEVARD BRIDGE REHABILITATION UPGRADING THE LOAD CAPACITY OF AN AGED TRUSS BRIDGE

With truss spans of 107.5 -7 @ 129 - 107.5, the 1118-long Boulevard Bridge is the link between communities on either side of the James River in the city of Richmond, Virginia. built in the early 1920s, this cantilever deck truss bridge showed its age and was in need of repair. The owner of the bridge, The Richmond Metropolitan Authority (RMA), after reviewing all the options, decided to rehabilitate the bridge to todays standards. Since there are not records for the steel material, the capacity of the bridge was carefully evaluated by interpreting the inspection results and material testing. By replacing the badly deteriorated elements and the missing rivets with high strength bolts, sandblasting and repainting the truss members, redecking with light weight concrete, and redesigning for new approach spans, the bridge was totally renovated and its life span extended. Critical analysis tools provided by the BEST Center and design decisions as well as construction alternation provided by HNTB made this rehabilitation project a success.
