Update 4:20 p.m. Monday: CHP calls off Sig Alert and re-opens bridge.
Update: 3:35 p.m. Monday: CHP calls for lanes leading to San Diego to be re-opened and for Coronado police to allow traffic to enter, following clearance of disabled vehicles from the bridge. No injuries have been reported.
Two collisions involving multiple vehicles have led to just one lane being open on the San Diego-Coronado Bridge, and none on the outbound side.
The CHP issued a SigAlert as of 2:45 p.m. with an estimate that it will take at least an hour to re-open the bridge to San Diego-bound traffic.
The incident began about 2:15, when the CHP, via its online traffic log, reported two cars had been involved in a wreck. An apparent chain reaction crash ensued, leading to an estimate of five to six vehicles being involved.
That was adjusted again, rising to up to eight vehicles.
The CHP called in Coronado police to assist in directing traffic away from the bridge and helping cars already there to depart the span.
The city reports, via Twitter, that the reason for backup on the Coronado-bound side is a rollover accident.
According to the CHP log, tow trucks are en route, and fire/rescue units have responded.
