About the Project
About the Imjin Parkway Widening & Roundabout Project
The City of Marina is performing improvements along the Imjin Parkway corridor, from Imjin Road to Reservation Road. The approximately 1.7 miles of roadway improvements include expanding the existing two lanes to four lanes, constructing four new roundabouts at intersections, and modifying the existing signal at the Reservation/Imjin intersection. Project amenities include class 2 bike lanes, a multi-use pathway, crosswalk beacons, storm-water improvements, street lighting, artwork, and landscaping.
