Traffic

The project team conducted an origin-destination study. This tracked vehicles as they entered and exited a specified area. This allowed the team to understand where vehicles were coming from and going. The information was used to find out how much existing traffic would likely use the freight corridor.

25 percent of morning and afternoon southbound trips

50 percent of morning and 33 percent of afternoon northbound trips

A map of Belfair showing a gray line, which represents the existing State Route 3, and a black line, which represents a new freight corridor. Two orange dots highlight the end of the new freight corridor. The graphic explains that 25 percent of morning and afternoon southbound trips would use the new freight corridor. It also shows that 50 percent of morning and 33 percent of afternoon northbound trips would use the new corridor.
25 percent of morning and afternoon southbound trips would use the new SR 3 freight corridor. 50 percent of morning and 33 percent of afternoon trips northbound would also use it.

Traffic volume forecast

The traffic volume forecast considered:

  • Historic traffic growth on SR 3
  • Anticipated growth related to development within the Belfair Urban Growth Area (UGA)
  • Anticipated growth related to development at Puget Sound Industrial Center (PSIC) in the Port of Bremerton

On an average weekday in May, traffic is expected to increase by 2.1 percent by 2028 and 3.3 percent by 2050 in the morning. In the afternoon, traffic is expected to increase 1.2 percent by 2028 and 4.8 percent by 2050.

Expected travel time savings

Once the freight corridor is built, travelers should expect to see their travel time cut by half or more. Travel time on the new roadway is expected to be six minutes in either direction.
