If you were planning to cruise northbound on Highway 99 Friday morning, you might want to check your watch again—and maybe your patience. Bridge construction between Modesto and Manteca turned the commute into a parking lot, with drivers facing delays stretching nearly two hours.
The culprit was bridge work over the Stanislaus River at Hammond Road. The project was supposed to wrap up at 5 a.m., but the crew ran over into the 6 a.m. hour, according to KCRA 3 traffic reporter Brian Hickey. That overtime meant northbound 99 got squeezed down to a single lane during the morning rush—exactly when thousands of people are trying to get somewhere. The backup stretched all the way back into Modesto and even snarled the Highway 132 connector, which felt the ripple effect of the gridlock.
At its worst, the travel time from Modesto to Manteca hit 95 minutes—an hour and 45 minutes for a stretch that normally moves far faster. Meanwhile, the rest of the region’s commute was humming along fine. Interstate 580 over the Altamont Pass clocked in at a reasonable 24 minutes, and Sacramento-area routes like I-5 and Highway 205 had no delays to speak of. But if you were stuck on that northbound 99 corridor, it felt like you were the only one.
The good news? Traffic cones eventually came down, offering relief to the delayed drivers. It’s a reminder that infrastructure work is necessary, even if the timing can turn a routine morning commute into a test of endurance. If you regularly drive that stretch, it might be worth keeping an eye on Caltrans alerts—especially during early morning hours when construction windows tend to happen. Better to know what’s coming than to sit through another 95-minute surprise.
