Three southbound lanes of the East Loop between Port of Houston and Manchester are currently closed and will now likely remain blocked through the end of the week.
Officials had hoped to have the repairs completed and all lanes open by Tuesday afternoon.
But the dense fog and weather conditions delayed work.
TxDOT officials say they found corrosion on a localized portion of the bridge during a routine inspection on Saturday, making the repairs necessary.
Crews are limiting the load on the bridge by restricting traffic to just two lanes.
Drivers traveling southbound on I-610 East Loop should detour to I-10 west to I-69 south to I-45 south to get back to I-610 southbound.
Drivers can also take Highway 90 southbound to I-45, or I-10 eastbound to Federal southbound and to SH-225 westbound.
