NE 18th Street Improvement Project

18th Street improvement project map

Four Seasons Lane to Northeast 138th Avenue

Construction Update: Installation of underground utilities is nearly complete on the south side of Northeast 18th Street, east of Northeast 125th Ave. Look next for the City's contractor, Tapani Underground of Battle Ground, to be grading and placing rock for widening the south side of 18th Street. Meanwhile, utilities installation continues along the north side of the street, also east of 125th Avenue. In addition, Clark Public Utilities will be working in the area to relocate power poles as part of this project. Work hours are generally 7 a.m. to 5 p.m., Monday through Friday but go as late as 8 p.m. if needed. Please go slow and be alert to possible lane changes. 

About this Project

Construction on this segment (1B) of the Northeast 18th Street Improvement Project began in late January, and is projected to be completed in early 2018. The project will improve vehicle and multi-modal usage along this heavily traveled corridor, particularly in the vicinity of the new Washington State Department of Transportation (WSDOT) interchange at NE 18th Street and Interstate 205.

The segment of NE 18th Street between Four Seasons Lane and NE 136th Avenue was originally developed as a narrow two-lane road and is now used by nearly 21,000 vehicles per day. Urban upgrades to the street will include additional travel lanes, improved traffic signal systems, and new bicycle and pedestrian facilities, including a dedicated pathway along the south side of 18th Street.

Construction Funding

Estimated cost of improving this segment of Northeast 18th Street is currently estimated at about $12.5 million. Construction funding will use a combination of development contributions, traffic impact fees, bonds, $6.5 million in federal grants approved through the local Regional Transportation Council (RTC), and $4 million from the State Transportation Improvement Board (TIB).

Construction Impacts & Updates

During construction, the City will work with its contractor to minimize disruptions to the extent possible. However, neighbors who live along Northeast 18th Street can expect some unavoidable but necessary inconveniences. There will be heavy equipment in the area, along with construction noise, delays, rough roads, detours and temporary lane changes at times. 

Advance notice of construction beginning and later paving will be provided to adjacent residents and nearby neighborhood associations. Updates will also be posted on Public Works' Facebook and Twitter channels.(See We appreciate your support and patience during construction so that we might provide you with an improved end result.

Project Need and Benefits

As residential and commercial growth continues east and west of Interstate 205, Northeast 18th Street is becoming more congested. Without improvement, it will be unable to accommodate future traffic demands. The goal of the improvements is to provide a safe and efficient multi-modal east/west connection across the city, offer ready access to emergency facilities, and alleviate traffic congestion on nearby streets. These improvements are projected to accommodate growth in the area over the next 20 years.

Meanwhile, the new state interchange at Interstate 205 and Northeast 18th Street is scheduled to open in July 2016, which makes completion of this segment of Northeast 18th Street even more critical.

Opportunities and Challenges

This project has presented some opportunities and unique challenges, including multiple layers of ownership interests in right of way needed through the Bonneville Power Administration corridor. In addition to agreed upon compensation for right-of-way acquisition, changes were made in the design and agreed to by both the City and Joe’s Place Farm, with the focus on keeping Joe’s Place Farm in business long after the project is constructed.

Opportunities include new walkways and the addition of bicycle lanes to increase pedestrian and bicycle safety, provide ADA accessibility and enhance the neighborhoods.

Further east, a frontage road will provide an alternative to multiple driveways along the street and the safety and traffic problem of cars backing onto 18th Street. While the frontage road is expected to enhance safety and screen residents from arterial traffic, it also has raised some questions from the Landover-Sharmel Neighborhood about potential traffic impacts at 126th Avenue, 129th Avenue, Village Green Drive and 134th Avenue. Although a traffic study has shown these intersections should operate acceptably for the next 20 years, the City has agreed to evaluate streets within the neighborhood, including Village Green Drive and 22nd Street, and install traffic calming and/or stop signs if warranted following the project.

Project Background

Improvement of this corridor has been a regional priority for many years. Beginning in the late 1970s when it was part of unincorporated Clark County, Northeast 18th Street has been identified as a major east-west arterial from 87th to 192nd avenues. A multitude of studies have been conducted, from 1986 to 2013, and all have reinforced the need for a five-lane street system between I-205 and Northeast 138th Avenue. 

Extensive public involvement was conducted from 2002 through 2010 during the environmental assessment and design of this project. The City's original project for the section from I-205 to 138th Avenue was split into two phases in 2010 due to funding constraints. Communications continued during construction of Segment 1A - the first segment from I-205 to Four Seasons Lane - which was completed in late 2011.  

Civil Designs, which are 100 percent complete for the segment from Four Seasons Lane to Northeast 138th Avenue, can be viewed in the Supporting Document section below. The Design Guideline report for the entire Northeast 18th Street corridor is also available below.
