Kittitas (pronounced 'KITT-i-tass') County is located in central Washington
State. It spans from the lush forested Cascade Mountains to the upper Yakima River Valley plains and
the Columbia River.
The county road system currently has 266 bridges and short span structures on system. Of these, 112 have a length of 20 feet or greater, which classifies them as bridges. Each year the county inspects approximately 50% of its bridges on an alternating basis to comply with National Bridge Inspection Standards (NBIS) requirement of a 24 month maximum inspection cycle. During these inspections potential problems and maintenance issues are identified and documented. These findings are scheduled for repair with either County Forces, WSDOT Bridge Crew or by contract. Routine inspections identify deficiencies early and corrective measures can be taken in order to eliminate a potential for major repairs or a hazard to the driving public. This program has been successful in identifying problems, quickly correcting deficiencies in county bridges and extending the life of existing bridges in county infrastructure.
This is a listing of all of the bridges on the county road system that have load limits posted less than legal loads.

The monitoring and inspection of County bridge conditions has been an on-going program for years
The Federal Highway Administration (FHWA) developed new calculations for determining the weight that a bridge can safely carry following a bridge collapse and, importantly, a recent decision by FHWA to allow heavier trucks on roadways. All state and local governments are evaluating publicly owned vehicle bridges using these new criteria and determining whether additional vehicle weight restrictions must be placed on bridges.
Key components of new method:
The county already has weight load limits on 15 bridges with another 2 bridges with shoulder closures.
Yes. There are approximately 600,000 bridges nationwide that must be reviewed under this new federal requirement. About twenty-five percent of these bridges are categorized as deficient: either structurally deficient or functionally obsolete.
Given that many of these bridges are aging and were designed when there was less traffic and smaller, less heavy vehicles, it is expected that a significant number of bridges nationally will require new weight load restrictions.
The county has contacted other jurisdictions throughout the state and has confirmed that they are also adding or anticipate adding vehicle weight restrictions to their bridge inventory as a result of the new federal requirements.
There are currently no plans to close any of the county’s bridges due to these new calculations, and we do not expect any closures, although we must complete all evaluations to be certain.
The load restrictions do not affect pedestrians, bicycles, cars, and typical passenger vehicles.
There will be no change to speed limits.
Truck companies and agencies can request the county to review specific delivery trucks for an over legal load moving permit for deliveries to dead end or otherwise inaccessible areas.
Many vehicles like school buses, fire engines and ambulances are still allowed depending on their weight and the loads they carry.
Kittitas County has a total area of 2,333 square miles. The highest point in the county is Mount Daniel at 7,959 feet above sea level.
