State law allows the Washington State Department of Transportation (WSDOT) to identify short, heavy-haul industrial corridors on state highways within port district property. These corridors allow for the movement of overweight sealed containers used in international trade. The maximum gross vehicle weight allowed on these corridors is 105,500 pounds. The heavier weight limits are authorized through a permit issued by the WSDOT Commercial Vehicle Services. Permits cost $100 per month or $1,000 per year.

The 2008 Legislature designated State Route 97 (SR 97) from the Canadian border to milepost 331.22 as a heavy-haul industrial corridor to allow overweight vehicles to be moved to and from the Oroville railhead. The maximum weight allowed on this route is 137,788 pounds.

Summary of Bill:

The heavy-haul industrial corridor on SR 97 is extended by one-tenth of a mile to milepost 331.12. The maximum weight limit allowed on this corridor is increased by 2,206 pounds to a total weight of 139,994 pounds.

Appropriation: None.

Fiscal Note: Not requested.

Effective Date: The bill takes effect 90 days after adjournment of the session in which the bill is passed.
