Construction work will cause intermittent full closures of state Highway 84 -- also known as Niles Canyon Road -- in Sunol in Alameda County between Palomares Road and Main Street in both directions each night from Tuesday night through Friday morning between 8 p.m. and 5 a.m.
Detours will be in effect and message signs will be in place to guide motorists. The closures will allow work on a replacement project of the Alameda Creek bridge. Intermittent nighttime closures are anticipated to continue through mid-June.
Caltrans advises motorists traveling from Palomares Road to take westbound Niles Canyon Road to Mission Boulevard, then take the on-ramp to northbound Interstate Highway 680, then take the eastbound Highway 84 exit.
Motorists traveling from Sunol and Pleasanton Sunol Road should take eastbound Niles Canyon Road to southbound I-680, exit on northbound Mission Boulevard, then take northbound state Highway 238 to westbound Highway 84.
