District 7 will use an innovative, rapid-set concrete mix over 2 weekends in October to speed repairs to the I-5 freeway bridge that was damaged in a fire this past July. This mix will cure in 6 hours instead of 36 hours, allowing the road to be closed for a shorter period. This mixture hardens quickly but cannot experience any vibrations during curing or it may crack requiring crews to rip it out and start over, so the freeway must be completely closed.
I-5 between Slauson Avenue and Paramount Boulevard will be completely closed Saturday nights October 17 and 24 beginning at 11 p.m. and re-opening Sunday mornings as late as 10 a.m., depending on the direction and date.
