Laying Cable Conduit on DMMD & S 200th

The City of SeaTac is partnering with the City of Des Moines to improve the intersection at Des Moines Memorial Drive South and South 200th Street.  Construction began in October, 2019 and will be complete by end of December, 2020.

 

Throughout the construction period, crews will be shutting down lanes along Des Moines Memorial Drive South and South 200th Street.  Single lane closures shall be between 9 AM to 3 PM.  However, some night time work is expected. Drivers are advised to find alternate routes during the entire construction period to avoid backups.

 The Project will include the following safety improvements:

  • New traffic signal and detection systems at intersection to trigger signal when cars are waiting
  • Left turn pockets, to improve traffic flow and make left turns safer
  • New sidewalks, concrete gutters and ADA curb ramps for wheelchairs and bicyclists
  • New bike lanes to create a separation between cyclists and car traffic
  • New street lights to improve driver and pedestrian visibility
  • Additionally, crews will underground utilities and upgrade stormwater infrastructure.
