DEFICIENT BRIDGES 28 WEIGHT-POSTED BRIDGES A weight-posted bridge is defined as a structure that has a rated loadcarrying capacity that is less than the designated legal truck weights in the state of Virginia. In Virginia, the maximum legal truck weight is 27 tons for a three-axle single unit vehicle and 40 tons for trucks with semitrailers. Structures are also posted if they have weight restrictions for fiveaxle, 45 ton vehicles that can obtain blanket operating permits, which are DMV-issued permits that allow an overweight truck to travel on any designated route throughout the state. Bridge inspectors impose weight restrictions on bridges as necessary for the structure to remain safely in service. WEIGHT-POSTED BRIDGES SUMMARY Bridges in Hampton Roads that have posted weight restrictions Hampton Roads rank among comparable metropolitan areas in terms of the percentage of bridges that have weight limits posted 102/8.3% 119/9.6% in 2007 11 th highest of 35 areas A total of 102 of the 1,223 bridges (8.3%) in Hampton Roads have weight limits posted. These bridges are shown in Table 6 on page 29. Many of these weight-posted bridges are on lesser traveled roadways; the only weight-posted bridges that carry over 10,000 vehicles per day are the Gilmerton Bridge and the Sunray Bridge (Military Highway over the Norfolk Southern Railroad near Bowers Hill in Chesapeake). Of the 102 weight-posted bridges, 22 are on Federal roadways such as the Colonial Parkway, Jamestown Tour Road, and Yorktown Tour Road. The number of weight-posted bridges in Hampton Roads has decreased since the previous Regional Bridge Study. In August 2007, 119 bridges in Hampton Roads had weight restrictions posted, which is 17 more bridges than are posted with weight restrictions as of August 2012. Compared to other metropolitan areas, Hampton Roads has a high percentage of weight-posted bridges. At 8.3%, Hampton Roads has the 11 th highest percentage of weight-posted bridges among the 35 metropolitan areas with populations between one and three million people.
