Caltrans will resume work Wednesday on the highway bridges over the Petaluma River after a request to halt the project was denied by a federal judge. Environmental groups sued in May, saying that netting designed to keep migratory cliff swallows away from the $130 million bridge project entangled and killed dozens of birds. Read Matt Brown’s story about the ruling HERE. Construction details will follow.

Caltrans also has plans to close the northbound U.S. 101 on-ramp from South Petaluma Boulevard on Monday, July 8, while temporary northbound on- and off-ramps are being built. The work will take about two months, making way for construction of a new highway interchange. Travel will be detoured north on Petaluma Boulevard South to the U.S. 101/State Route 116 interchange.
