ROADS AND TRAILS

20th Street SE, 91st Avenue SE to South Lake Stevens Road, Snohomish County, Washington

This project included widening 20th Street SE and channelization improvements on SR 9. Improvements included widening for additional through and left turn lanes, bike lanes and sidewalks, signals, illumination, and associated stormwater facilities. ABKJ completed the stormwater management feasibility report that analyzed two levels of water quality treatment, right-of-way impacts, sensitive area impacts, comparative construction costs, and long-term maintenance.

Little Mashel Trail, Eatonville, Washington

This project includes developing a 3-mile recreational use trail with two river crossings. The bridges and trail alignment will serve as a connection between the Town of Eatonville and the University of Washington Pack Forest. ABKJ completed a Preliminary Bridge Study and led the PS&E design, which included pervious pavement to address stormwater requirements.

Port of Seattle Duwamish Trail, Seattle, Washington

This project connected the Duwamish Trail on West Marginal Way SW with the Alki Trail in West Seattle. This one-mile trail extension enables users to travel on a continuous trail from Alki Beach Park to the 1st Avenue South Bridge over the Duwamish River. ABKJ led a multidiscipline team for the final design (PS&E) and prepared the civil roadway and trail design.

SR 9 Widening, Lundeen Parkway to SR 92, Snohomish County, Washington

This project widened a section of SR 9 from two lanes to four lanes. Existing wetlands downstream were purchased and preserved to provide natural retention and detention for SR 9 runoff. The ABKJ design reduced construction costs by $3 million and eliminated elevated temperature concerns for downstream fish typically associated with conventional detention pond discharges.

SR 161 Widening, 176th Street to 234th Street, Pierce County, Washington

This project included widening and improving approximately 3.8 miles of SR 161. ABKJ was responsible for preparing preliminary engineering and independent PS&E packages for the improvements to SR 161 from 176th Street to 204th Street and 204th Street East to 234th Street East.

SR 522, Stages 2 and 5 - Widening and Fales Road Interchange, Snohomish County, Washington

These projects included widening 8.5 miles of SR 522 from two to four lanes. ABKJ led the stormwater design, including seven major fish passage culverts in fill sections up to 45' deep and drainage and temporary erosion control PS&E. These combined projects consist of more than 15 miles of roadway development surrounded by wetlands, stream crossings, and environmentally sensitive areas.
