Rainbow Bridge Closure

Update, June 22:  Work continues on the Rainbow Bridge with anticipated completion Friday at 5 p.m. The contractor will continue the polyester concrete bridge overlay Wednesday night due to high temperatures during the day.  Additional roadway paving will occur during the daytime Thursday, and pavement delineation and placement of expansion joints will take place during the daytime hours on Friday.


Major repair work to protect and preserve the century-old Rainbow Bridge in Folsom will require a full closure from Monday, June 20 at 6 a.m. to Friday, June 24 at 5 p.m. Riley Street will be closed between Scott Street and Greenback Lane at Folsom-Auburn Road. Motorists can expect traffic delays, and are encouraged to take Lake Natoma Crossing to Natoma Street to Riley Street as an alternate route. Detours will be clearly marked and message signs will alert motorists in advance of the closure before work begins. Local access will be available for Sudwerk’s Grille, the bicycle trail on the north side, and to the Powerhouse State Park. 

Rainbow Bridge, which spans the American River at Greenback Lane, has provided a major connection for businesses and residents on both sides of Lake Natoma for nearly 100 years. More than 25,000 motorists cross the bridge daily. Work will include bridge resurfacing, barrier rail repairs and pavement repairs on the roadway approaching the bridge.

The closures are necessary to perform work on the Rainbow Bridge Maintenance Project. The rehabilitation project will extend the lifespan of the historic bridge and provide a smoother and safer drive for motorists. The $1.1 million project is funded largely by a federal grant administered by the Caltrans Bridge Preventative Maintenance Program. The project will be completed by October 2016. No other daytime closures are anticipated after June 24. Stay informed about closures and detours at www.folsom.ca.us.
