Caltrans completed its work on time on Interstate 805 and by the freeway was back open for commuters early Monday.
After a 14 hour-long closure, all lanes were reopened shortly before 4:30 a.m.
Interstate 805 was closed from State Route 54 to State Route 905 as crews demolished the East Palomar Street Bridge.
The demolition has cleared the way for a Direct Access Ramp, or DAR.
The project will create carpool lanes, bus lanes and expressways that will help move traffic through this busy area.
"We have about 141,000 cars on average traveling the corridor,” said Cathryne Bruce-Johnson. “We expect congestion to increase up to 40-percent in next 20 years."
Chula Vista resident Richard Rodriguez was willing to put up with the inconvenience.
“Will definitely help with as big as our city is growing we need something like this on our freeways," he said.
CALTRANS has a similar project planned for I-5 in North County at a later date.
