2013-2014 Arterial Paving Projects: N 105th, N/NE Northgate Way Improvement Project

Updated: 04/30/13

Project Overview

The Seattle Department of Transportation (SDOT) is planning roadway improvements along N 105th Street and N/NE Northgate Way from Greenwood Ave N to Lake City Way NE. SDOT will complete final design of the project by the second quarter of 2013. Construction is scheduled to begin Summer 2013 and is anticipated to continue through Summer 2014.

The project is funded by the “Bridging the Gap” transportation levy approved by Seattle voters in November 2006 and the Washington State Transportation Improvement Board. 

Project Description

This project will improve the corridor along N 105th Street and N/NE Northgate Way from Greenwood Ave N to Lake City Way NE. Improvements will include roadway repaving, new sidewalks and curb ramps, drainage improvements, street lighting and traffic signals, and Intelligent Transportation System (ITS) components.

Roadway improvements include:

• New paving on the roadway from Greenwood Avenue N to Corliss Avenue N.
• New drainage infrastructure, including new stormwater detention pipes and water quality features.
• New five-foot-wide sidewalks and curb ramps.
• New roadway markings.

Signal, lighting and ITS improvements include:

• Eight new street lights between Greenwood Avenue N and Corliss Avenue N.
• New dynamic message signs (DMS) at N 105th Street/Evanston Avenue N and Lake City Way NE/NE 120th Street.
• New closed-circuit TV cameras to help with traffic management and safety, at Greenwood Ave N/N 105th Street, Ashworth Avenue N/N 105th Street, and Meridian Avenue N/N Northgate Way.
• Seven new cameras that provide real-time traffic information to web-based systems and the DMS signs.

What to expect during construction:

This project will have considerable impacts on traffic and the public. SDOT will conduct outreach to residents and businesses in the neighborhood beginning in Fall 2012 until project completion to ensure that they have the information they need to cope with construction.

When this project is completed, it will have significant benefits for the public and motorists, including:

• Improved safety for pedestrians.
• Elimination of potholes.
• Eased traffic congestion.
• Improved water quality.
• Transit speed and reliability.
• Real-time information for travelers.
