Weigh/Inspection Station Options

The project team has looked carefully at six different locations for a new weigh and inspection station on eastbound I-90. The original scope of the project required that the new weigh and inspection station serve eastbound traffic on I-90 and be located between the 436th Avenue Southeast and 468th Avenue Southeast interchanges. The project team has looked beyond that limited scope in an effort to respond to stakeholders’ concerns about locating a new weigh and inspection station in the vicinity of North Bend.

Of those six potential locations, four have been eliminated due to cost, leaving the sites at Milepost 33.5, at 468th Avenue Southeast, just outside of North Bend, and at Milepost 80.3, just outside of Cle Elum. For each of these, the project team is considering two layouts.

In addition to these two locations, the project team is currently looking at the feasibility of siting the weigh and inspection station at Milepost 45.5, near the Bandera Airfield. If that site is shown to be workable and cost effective, the potential layouts would be similar to what is shown below.

Milepost 33.5

Milepost 33.5 Linear Layout

Milepost 33.5 linear is located near 468th Avenue, just outside of North Bend.

It meets the project requirements of being east of the interchange, and it supports the Washington State Patrol’s goals of enforcing safety, facilitating chain-up and being easy to staff. It does not require the purchase of right-of-way and it does not impinge on significant wetlands or lead to a lot of mitigation work.

In this configuration, we have respected requests for a minimum amount of parking, and trucks are discouraged from going through town to avoid the weigh station thanks to bypass detection technology. Underground storage vaults help manage run-off and improve drainage. A tree buffer along the frontage road minimizes the view of the weigh and inspection station.

Milepost 33.5 Linear East Layout

Milepost 33.5 linear east is located near 468th Avenue, just outside of North Bend. In this configuration the body of the station moves closer to 468th Avenue.

It meets the project requirements of being east of the interchange, and it supports the Washington State Patrol’s goals of enforcing safety, facilitating chain-up and being easy to staff. It does not require the purchase of right-of-way and it does not impinge on significant wetlands or lead to a lot of mitigation work.

In this configuration, we have respected requests for a minimum amount of parking, and trucks are discouraged from going through town to avoid the weigh station thanks to bypass detection technology.

This configuration lowers the cost of managing draining by using fewer underground water storage vaults and maximizing the use of natural drainage to manage water on-site. It also moves the weigh and inspection station away from Camp Waskowitz and the Camp Waskowitz well head.

Milepost 80.3

Click and drag the two-way arrow to see how the new design option looks.

Milepost 80.3 Linear Layout

Milepost 80.3 linear is just outside of Cle Elum, across the freeway from the westbound weigh station.

This location meets the project requirement that the weigh and inspection station be located east of the I-90/SR 18 interchange. Washington State Patrol does not believe they will be able to fully staff an eastbound weigh and inspection station at the same location. An eastbound weigh and inspection east of the pass would not facilitate safe chain-up before the pass.

Milepost 80.3 Circular Layout

Milepost 80.3 circular is just outside of Cle Elum, across the street from the westbound weigh station.

This location meets the requirement that the project be east of the I-90/SR 18 interchange and it is in the existing right of way. The circular design makes it easier for trucks to be weighed multiple times without re-entering the highway.

Washington State Patrol does not believe they will be able to fully staff an eastbound weigh and inspection station at the same location. An eastbound weigh and inspection east of the pass would not facilitate safe chain-up before the pass.
