CHANNEL CLOSURES
FULL CHANNEL CLOSURE
Both north and southbound channels will be closed starting at 5am on Tuesday, June 8, 2021 and will remain closed through noon on Saturday, June 12, 2021. The south channel will re-open at or before noon.
NORTH (INBOUND) LANE CLOSURE
The north (inbound) channel will remain closed starting at noon on Saturday, June 10, 2021 through noon on Monday, June 14, 2021. The north channel will remain closed while equipment demobilizes.
Please be advised that when one channel is closed, the other channel will have two-way vessel traffic. The two-way traffic will be managed as follows:
Traffic will be directed by a green and red signal on each side of the channel, indicating allowed direction of travel in the channel based on time. The time interval is 5 minutes per direction. This is based on feedback from the boating community and the U. S. Coast Guard.
Flagging vessels plan to use radio channel 16 to communicate with approaching vessels. Please pay attention to the radio and to message boards near the channel for any updates.
Flaggers on boats will direct traffic during daylight hours on Saturday and Sunday, or as directed by the U.S. Coast Guard.
For full channel closures, we anticipate having additional resources on site to assist with vessel traffic.
To assist boaters in navigating through the correct channel, chains of red/orange round buoys will be placed delineating the edge of the travel to the open channel, and prevent boaters from entering the closed channel.
At various times law enforcement assets will be on-scene to included Galveston County Sheriff’s Marine Division and U.S. Coast Guard to ensure adherence to this marine traffic management plan.
Message boards will be placed on both approaches to the channel to assist with notifying approaching vessels.
Full closure: the full closure listed in the table above means that the channel will be fully closed to all vessel traffic for the duration of that closure. This is necessary because concrete bridge girders will be lifted and set on the bridge, and vessels can not pass under this operation for safety reasons.
In case of emergency, the crews can coordinate with emergency vessels to see if accommodations can be made.
U.S. Coast Guard Restrictions – both channels will be fully open for the following events:
Texas Outlaw Challenge: 6/25/21 through 6/26/21.
Youth Race Week: 7/8/21 through 7/11/21.
In the event that there are severe tropical storms, the contractor will remove and secure their equipment and re-open both channels until the weather subsides.
