Project Description

Phase 1 of the 24th Avenue S corridor improvements (current TIB request) will widen 24th Avenue S between Kent-Des Moines Road (SR 516) to S 223rd Sttreet. The project will include sidewalks, bike lanes, reduced travel lane widths for traffic calming, two-way left turn lane, storm drainage, and illumination. Pedestrian safety will be improved by the construction of ADA sidewalks on both sides of the roadway and enhanced pedestrian crossings specifically near Midway Elementary, Pacific Middle, and Mt Rainier High Schools. Safety and mobility for all modes of transportation will be improved where very limited or no opportunities currently exist.

Existing Condition

The 24th Avenue S corridor project is a critical north-south arterial roadway between Kent Des Moines Road and S 216th Street providing continued access to the Sound Transit light rail station at S 200th St and to SeaTac Airport at S 188th Street. Two public schools, multiple churches, Des Moines Creek Business Park, and FAA facilities are all accessed from 24th Avenue S. Upon recent completion of the Connecting 28th Avenue/24th Avenue S project in SeaTac, traffic volumes have increased more than 30% within the project limits as traffic patterns have shifted from SR 99 and SR 516/SR 509. Residential single family land use comprises much of the project and the existing lack of sidewalks, narrow shoulders, and deep roadside ditches combined with increased traffic volumes contribute to an unwelcoming environment for non-motorized users. The motorized and non-motorized demand is expected to significantly increase over the next 20 years as users bypass SR 99 and SR 516/SR 509. The time for action is now to improve the safety and mobility of this corridor especially for non-motorized users.
