Did you know that Road Services is going to remove the weight limit restriction on some of our bridges in unincorporated King County? It’s true. Seven bridges (see the list at the bottom of the post) will soon be open to heavier trucks such as large fire engines and hauling vehicles. Work to remove the posted weight limit signs starts this week. It may take up to two weeks to take down all seven signs.
Why is Road Services removing the weight limit?
The Federal Highway Administration (FHWA) sets the standards for determining the weight a bridge can safely carry. The FHWA revised the weight limit standard in 2013. Since then, county bridge engineers carefully evaluated all the bridges maintained by King County to determine whether weight restrictions on some of the bridges could be removed.
Our engineers found that most of the bridges do need to remain load restricted, however the seven spans that are supported by “precast concrete channel beams” can handle more weight.
When will the weight limit get removed?
Road Services will remove the posted load limit signs on the seven identified bridges by the end of June 2022. Once the posted weight limit restriction signs are down, the bridges will be open to all vehicles.
