Old Belfair Highway (OBH) was a State Highway at one time and was originally built to state standards. It functions as an arterial serving intra-county travel from Bremerton to Belfair and points beyond. OBH is an important highway and parallels SR-3. It serves as an important detour during incidents occurring on either route and provides additional capacity for traffic coming to and from the Tahuya Peninsula.


This project was submitted to widen and realign Old Belfair Highway between and to extend an existing arch culvert as well as improving the roadway geometrics. After a closer evaluation of the engineer’s estimate, the type of work to be done, and the amount of work that could be accomplished, it was determined that the project limits could be extended without increasing the necessary funding. The road was paved, five-foot paved shoulders were provided (originally 3-to-4-foot gravel soft shoulders), the guardrail systems were upgraded, and new traffic barriers were installed, and the lane widths increased.
