A. PROJECT DESCRIPTION / BACKGROUND
Interurban avenue is an arterial varying between two lanes and five lanes. The project
limits extend from approximately 100' south of East Marginal way S to 100' north of S
1431 St. The project is approximately 2.25 miles including 9 signalized intersections, 10
unsignalized intersections and numerous driveway approaches. Due to heavy vehicle
traffic and high traffic volumes the asphalt pavement has deteriorated to various degrees
and requires rehabilitation. Some ADA ramps and pedestrian push buttons within the
project footprint appear to not meet current ADA requirements and will require
replacement and/or maximum extents feasible documentation. Traffic loops within the
grind and overlay limits will require replacement or upgrades to video detection.
This project has Federal National Highway System funds for both design and
construction. Additional local funds may be used for portions of the project that ara.
outside of the NHS funds scope.
