The Major Streets Transportation Improvement Program (MSTIP) is Washington County's innovative, proactive street improvement program.
This countywide program has funded more than 160 transportation improvements in cities and unincorporated areas throughout Washington County. These projects help people travel safely and reliably, whether they walk, roll, bike, take transit, or drive.
MSTIP projects focus on:
- Improving safety
- Reducing congestion and improving overall traffic flow
- Supporting multimodal access for all travelers
- Serving major streets used widely across the county
- Supporting people of all ages, abilities, and travel modes
MSTIP project funding goes directly back into our local economy through contracts with local planning and engineering firms and construction contractors who design and build MSTIP improvements under County supervision—powering our local economy and supporting hundreds of jobs.
The Washington County Board of Commissioners demonstrated a strong commitment to a connected, safe, multimodal countywide transportation by:
- Authorizing the issuance of $150 million in debt obligations to address an unprecedented funding gap due to transportation project cost escalations.
- Approving a $250 million MSTIP 3f funding allocation including 13 projects in both the County and the cities within the County.
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 across Washington County.
The County and cities within the County have leveraged about $63 million in external funding using $12.5 million in in funds. Learn about the MSTIP Opportunity Fund.
Washington County and the cities of Beaverton, Hillsboro and Tigard developed the MSTIP Bonding Cost-sharing Program to improve existing arterials in four high-growth residential areas developing simultaneously.

A History of MSTIP
MSTIP began as voter-approved levies in 1986 (MSTIP 1), 1989 (MSTIP 2) and 1995 (MSTIP 3). In 1997, Oregon Measure 50 resulted in the MSTIP 3 levy rate being reduced and incorporated into a new permanent County property tax rate. Since Measure 50 implementation, the Board of County Commissioners has allocated a share of countywide property tax revenues for an ongoing MSTIP program.
Direct and leveraged funding has resulted in more than $1.35 billion in transportation projects in both Washington County and the cities within the county since 1986. The County and the cities within the County work collaboratively to develop a list of potential capital projects for public comment. After reviewing all comments, the County and cities' staff develop a "top tier" list and present it to the Washington County Coordinating Committee. This committee makes final recommendations that are submitted to the Board for final approval of the allocation and projects.
Most of the money goes back into our local economy. Private-sector planning, engineering firms and construction contractors design and build MSTIP project under County supervision. These businesses are selected on a competitive-bid basis.
