Project Facts

This project paved 7.27 miles of State Route 4, from Coal Creek to I-5.

This section of highway was last paved between 1979-1990.

The majority of this project was constructed at night to minimize traffic impacts.

This project paved State Route 4, from Coal Creek to I-5. The project began at the Coal Creek Slough Bridge (milepost 50) and travels east through Longview along the Ocean Beach Highway, turning north at Washington Way onto Cowlitz Way, then across the Peter Crawford Bridge, including the one-way couplets on 4th and 5th Street in Kelso, then east on Allen Street, under the I-5 crossing and ends at the intersection of Kelso Drive.

This section of SR 4 was in need of resurfacing, as several intersections had severe rutting from heavy traffic, resulting in numerous spots of deteriorating pavement.

The pavement was beyond its useful life span and in need of repair. Through this project, safety improvements were made to this portion of the roadway to keep this busy road in working condition.

The safety upgrades made during this project include improved sidewalk ramps to ADA standards, replacement of non-standard guardrails, upgrades to median barrier curbs, restored pavement markings and replaced signs.

How You Benefit
Cross GlyphImproves Safety
Improves driver safety by eliminating cracks, potholes and rough patches, improves reflectivity of pavement markings, and provides for a consistent driving surface. These improvements also included improved sidewalk ramps to ADA standards, replacement of non-standard guardrails, upgraded to median barrier curbs, restored pavement markings and replaced signs.
Leaf Glyph Protects Environment
To minimize adverse effects on the environment, crews used erosion control measures to ensure sediment and debris did not leave the project site or enter the drainage system. These measures included the use of inlet protection and street cleaning.

Partnerships & Cooperation
WSDOT makes every effort to assess and minimize environmental impacts from our projects. A detailed analysis of the project’s environmental impacts was completed as part of the environmental documentation and environmental permitting processes.

The Biological Assessment (BA) was completed in March 2006, and the State Environmental Policy Act (SEPA) Assessment was completed in August 2006. In September 2006 a shoreline exemption was permitted. The environmental evaluation has been completed.

The project was first introduced to the public at an open house on April 4, 2006. A second open house was held Jan. 18, 2007 at the Cowlitz PUD in Longview, Wash.

Additional public involvement opportunities occurred prior to construction. Advance notification about any opportunities was sent out to area residents, businesses and local media, and posted on this Web page for additional public outreach efforts.

At WSDOT we seek to address the concerns of the tribal nations using the process outlined in Section 106 of The National Historic Preservation Act and the WSDOT Tribal Consultation Policy adopted in 2003 by the Transportation Commission as part of the WSDOT Centennial Accord Plan.
