Night-time lane restrictions will start back up on the twin bridges. The contractor on the rehab project plans to reduce southbound traffic to one lane starting Monday from 7 p.m to 6 a.m. This will last all next week. For the last two and a half months they have been able to keep both southbound lanes open at night. Just a reminder for drivers, a strict 35 mile per hour speed limit will be in effect. If you get caught speeding, expect to pay double.
