Update: Southbound I-5 to close at 8 p.m. after morning gas tanker crash in Sacramento

3 p.m. update: Caltrans and the CHP North Sacramento office said in tweets that all lanes of southbound Interstate 5 will be closed at the I-80 interchange at 8 p.m. for about three to four hours for emergency work following the 10 a.m. big-rig crash near Richards Boulevard.

The right lane and the on- and off-ramps at Richards Boulevard on southbound I-5 remain closed as of 3 p.m.

Original story:

An Interstate 5 on-ramp and off-ramp in downtown Sacramento are closed after a big-rig gas tanker crashed off an overpass, spilling fuel, but no injuries have been reported, according to the California Highway Patrol and Sacramento police.

The collision was reported just after 10 a.m., when a semi truck traveling southbound on I-5 veered off the freeway at or near the Richards Boulevard overpass, overturning and rolling down an embankment on the right side, according to the CHP’s traffic incident log.

The driver exited the vehicle and was reportedly uninjured, according to the CHP log, but the truck was “leaking fuel.” Sacramento Fire Department personnel were dispatched to the scene for active hazardous materials work, the department said in a tweet.

Sacramento police Capt. Norm Leong confirmed in a tweet that the I-5 on-ramp is closed due to an overturned truck.

Just before 10:30 a.m., Caltrans tweeted that the southbound off-ramp to Richards Boulevard has also been closed. No estimated time of reopening has been given.
