From time to time our construction and maintenance projects require temporary road or lane closures, trail closures or similar impacts to vehicular or pedestrian traffic. Current and planned impacts will be noticed here.
Current Trail Impacts
West Little Llagas Creek Trail Temporary Closures (Morgan Hill)
Trail Entrances at Edes St., Cosmo Ave., and Spring Ave. temporarily closed
For public safety, beginning the last week of April through mid-September 2025, the entrance to West Little Llagas Creek Trail at Edes St. will be closed, and the entrance at Cosmo will close early May through mid-July 205 to accommodate construction activity. The trail entrance at Spring Ave. will close mid-July 2025 and remain closed through mid-October 2025.
Trail users can access the trail at West Edmundson Ave. and continue south. Del Monte Ave., Olympic Dr., and Monterey Rd. will serve as detour routes. Click here to view the detour map and closure locations.
W. Middle Ave. to Monterey Rd.
Beginning May 1, 2025, through mid-month, the east side of the West Little Llagas Creek Trail will be closed from W. Middle Avenue to Monterey Road, to accommodate the installation of a dewatering system in Llagas and West Little Llagas creeks. The west side trail at W. Middle Avenue to Lake Silveira will remain open. To view a map or to learn more about the project, click here.
For the safety of trail users and workers, the trail must be closed. Crews are scheduled to work weekdays from 7:00 a.m. to 8:00 p.m. They’ll be staging equipment, materials and trucks on the trail. Those trucks will also drive throughout the closed trail. The dewatering system diverts water from Llagas Creek to West Little Llagas Creek, where it will recharge groundwater aquifer.
Stream Maintenance Program (2025)
As part of our Stream Maintenance Program (SMP), Valley Water performs work along creeks across Santa Clara County every summer. Under the SMP, work occurs annually to improve the environment, reduce flooding risk, and keep our communities safe. For decades, our crews have been trekking into streams to remove sediment build-up, manage vegetation, clear trash and debris, and stabilize banks that have eroded during high water flows. For the public's safety, work crews and to complete this vital community work, on occasion, trails will be temporarily closed.
Guadalupe River East Trail between Montague Expwy. and Trimble Rd. Levee Maintenance Work
Beginning April 21, 2025, the Guadalupe River east levee trail between Montague Expwy. and Trimble Rd. in San Jose will be closed for approximately two weeks to accommodate levee repairs. Crews are scheduled to work weekdays from 8:00 a.m. to 3:30 p.m. The trail will reopen at the end of each workday and remain open on the weekends. Please use the west levee trail.
The trail must be closed for the safety of trail users and workers. Equipment and materials will be staged on the trail, with heavy equipment driving up and down the closed section.

Current Traffic Impacts
As a safety reminder, please use caution when driving near construction areas and follow all traffic control measures and detours, including signboards, devices, and flaggers, to safely detour nearby drivers and pedestrians.
Hale Avenue Temporary Closure April 14 through October 2025 in Morgan Hill
Work on Hale Avenue continues as part of the Upper Llagas Creek Flood Protection Project. Crews will resume the construction of twin box culverts beneath Hale Avenue, starting from the Morgan Hill Shopping Center and moving towards Wright Avenue. A box culvert is similar to a square-shaped underground tunnel. The two 10-foot wide by 9-foot high culverts will replace West Little Llagas Creek along the eastern side of Hale Avenue to convey a 100-year storm, which has a 1% chance of occurring once a year.
Crews will work from 7:00 a.m. to 8:00 p.m. Monday through Friday and 9:00 a.m. to 6:00 p.m. on Saturdays. Hale Avenue will remain closed through October 2025. Access to the Morgan Hill Shopping Center remains open on Main Avenue, but access from Hale Avenue is only open from the first driveway near the donut shop. The entrance to the Park Plaza Professional Center will be on Crest Avenue. Please see the attached detour map.

Spring Avenue in Morgan Hill
Work on Spring Avenue from West Little Llagas Creek to Monterey is forthcoming. Turns to and from Monterey Rd will be limited. Additional details are forthcoming.
