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
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.
