The Major Streets Transportation Improvement Program (MSTIP) is our innovative, proactive road improvement program. MSTIP funding improves our transportation system for bicyclists, pedestrians, drivers and transit passengers.

The MSTIP Opportunity Fund leverages other local, state and federal funds. We use it for projects that improve travel for those who walk, bike, roll and take public transportation. 

MSTIP began as voter-approved levies in 1986, 1989 and 1995. In 1997, Oregon Measure 50 resulted in the MSTIP levy rate being incorporated into a new permanent County property tax rate.

Direct and leveraged funding has resulted in more than $1 billion in transportation projects in both Washington County and the cities within the county since 1986. The Washington County Coordinating Committee recommends projects. The Board of Commissioners then approves funding amounts and projects on five-year cycles.

Most of the money goes back into our local economy. Private-sector planning, engineering firms and construction contractors build MSTIP project under our supervision. These businesses are selected on a competitive-bid basis.
