March 29
The 710 off-ramp was fully closed and traffic was diverted to the Del Mar Blvd. off-ramp causing delays and headaches for commuters. The first full ramp closure was in place until temporary repairs were completed in the overnight hours. Once the temporary repairs were completed, the ramp was reopened but restricted to a single lane. This resulted in traffic delays during the peak during morning and afternoon commuting hours.
March 30
The lane closure on the ramp remained in place until materials could be acquired and repairs completed. This resulted in traffic delays during the peak during morning and afternoon commuting hours. With rain in the forecast , the contractor anticipated the repairs would be completed on or before Tuesday, April 4th.
March 31
Pasadena contractors patched the pavement, and the southbound ramp to California Blvd was re-opened by 3:00 pm on Friday, March 31.
April 1 and 2
The ramp remained fully open for the weekend.
April 3
Another single lane closure on the ramp began at 7:00 am. This closure allowed the contractor to prepare the site for pipe lining. The contractor intended to close only one of the two lanes on the ramp so traffic could still get through. Commuters experienced some delays.
April 6
The City of Pasadena contractor plans to be back Thursday morning to perform additional work. This will require a full ramp closure for the SB 710 ramp to California Ave which will begin at 7:00 am. The intent is to have the process complete and the ramp fully re-opened by 4:00 pm (updated).
April 7
The contractor will be back one final time on Friday morning to finalize the work. This will require a single lane ramp closure that will begin at 7:00 am and will be complete by 3:00 pm.
This should complete the repairs at this location.











Imagine the disaster if it was a fully functioning freeway!
