The Bow Hill Road Project consists of 0.61 miles from Old Hwy 99 North to Darrk Lane. Due to sloughing of the embankment on the south side of the roadway, the existing roadway and base will be removed and stabilized. The existing guardrail will need to be removed and replaced and terminal ends added. Drainage will need to be maintained or improved.
This segment of Bow Hill Road is a T3 truck route with a truck percentage of 7%. Bow Hill Road provides access to the I-5 interchange approximately 0.3 miles west of Darrk Lane and moves traffic traveling from the north on Old Hwy 99 North and from the east between SR9 and I-5. This route is an important economic route for Skagit County that provides movement of traffic from various rural areas of the County along with providing access to numerous businesses, gravel pits, an asphalt plant, and a concrete plant.
The current roadway deficiencies to be improved are: 1) deteriorating sub-grade, 2) deteriorating surface and shoulders, 3) stabilization of the lower embankment, and 4) drainage. This project will widen the current pavement width to meet the 40 foot pavement width as geographic restrictions allow. We will also improve barrier protection, guardrail terminal ends, and sub-grade engineering.
