SW Barbur Court Off-Ramp Will Close
Construction has started on a series of terraced stormwater rain gardens and collection pipes to protect Tryon Creek water quality and prevent stream bank erosion. Beginning Tuesday, August 19, the SW Barbur Court off-ramp will close during daytime work hours to allow construction crews to unload and install prefabricated, concrete vaults.
The off-ramp will close from 7:00 a.m. to 4:00 p.m. Monday through Thursday and will re-open to traffic after work hours. This phase of the project should be completed by Wednesday, August 27. See the map below and the reference number 3 for the location of the work. Please be aware that this schedule is subject to change due to conditions underground, weather, traffic impacts, subcontractor schedules and availability of materials.

You will be notified before works starts at each location.
When it rains, stormwater runoff from I- 5, SW Barbur Boulevard and SW 26th Avenue drains directly to Tryon Creek. Stormwater runoff carries pollutants to the creek, and high runoff volume and velocities erode stream banks. The rain gardens will collect sediments and pollutants before the water enters Tryon Creek. This project also includes installing new pipes that will direct stormwater from various locations into these facilities for filtration. This project will protect Tryon Creek water quality and help prevent stream bank erosion.
