Macadam Road South Watermain Upgrade and Sidewalk Improvements
This project will Design and construct 4,300 LF of 10″ waterline in Macadam Rd S from S 144th St to Southcenter Blvd to Improve fire flow water quality to the north side of Tukwila Hill.
Approximately 1,200 feet of concrete sidewalk will also be installed along Macadam Road S where no sidewalk currently exists to increase pedestrian safety and accessibility. Drainage improvements and new pavement and striping are part of the project to be constructed by Laser Underground and inspected by the City of Tukwila and PACE Engineers.
Starting February 22nd, Macadam Road from 144th Street to Southcenter Boulevard will see frequent closures, reducing it to one lane during working hours for the next four to five months. Contact Metro if you suspect your bus stop is impacted. Pedestrian access will remain open as much as possible. The improvements include upsizing and looping the dead-end, undersized watermain that was built in 1970. New hydrants and valves will be installed to improve fire flow.
If you have any questions or concerns, please contact Adib Altallal at Adib.Altallal@TukwilaWA.gov.
