SIG ALERT ON WB SR-94:
A tractor fell off a semitrailer on westbound state Route 94 near 28th Street, blocking at least two lanes and snarling traffic in the area.
The incident happened just after 9 a.m., and the California Highway Patrol says the issue has prompted a Sig Alert expected to last 90 minutes.
There is no word on what caused the tractor to fall from the semitrailer.
No injuries were immediately reported.
Construction to cause I-5 delays in La Jolla Wednesday and Thursday evenings
SAN DIEGO -- Crews will begin working Wednesday night to place temporary concrete barriers and restripe lanes on the Interstate 5/Genesee Avenue interchange, which could lead to traffic delays.
From 7 p.m. Wednesday to 5 a.m. Thursday and again Thursday to Friday, up to three lanes of the northbound and southbound freeway will be closed intermittently between Voigt Drive and Sorrento Valley Road, according to Caltrans.
The southbound Roselle Street on-ramp and the Interstate 5/Genesee Avenue on- and off-ramps will also be closed intermittently.
The work is scheduled to pick up again on Sunday, and intermittent lane closures on the northbound freeway will occur between Genesee Avenue and Roselle Street, Caltrans said.
Caltrans officials said delays were to be expected and advised motorists to avoid the area if possible.
The work is part of a $105 million project to replace the existing Genesee Avenue overcrossing with a 10-lane structure. It is expected to be completed in 2017.
