Eastbound Interstate 8 between El Cajon and Alpine will be closed for six hours tonight due to a CHP investigation, the California Department of Transportation (Caltrans) announced.
Caltrans officials said the I-8 would be closed between Dunbar Lane/Harbison Canyon Road in El Cajon to Tavern Road in Alpine from 11 p.m. Monday until 5 a.m. Tuesday.
According to Caltrans, the closure is needed so that CHP officials can conduct a traffic investigation.
CHP is investigating a June 11 collision in which Calexico teacher Jimmy Arevalo and UCSD student Angela August were killed, allegedly by suspected at-fault driver Sunny Hall.
Motorists traveling eastbound on I-8 will be detoured onto Old Highway 80/Alpine Boulevard at Dunbar/Harbison Canyon Road and back onto I-8 at Tavern Road.
Posted detour signs will help guide traffic.
