Northbound I-410 closure this weekend

We've gotta be honest - this one got jumbled in our schedule a bit. This alert should have gone out at least two days ago. It didn't. That's entirely on us and a schedule oversight this week.

Williams Brothers Construction will close all lanes of northbound I-410 between US Hwy 90 and Hwy 151 Saturday at 2 a.m. until Monday at 5 a.m.

This closure follows a brief overnight closure of southbound I-410 between Hwy 151 and US 90 starting tonight at 8 p.m. going until about 2 a.m. tomorrow. Only one direction of traffic will be closed at a time.

Here's the closure narrative in our traditional format:
  • Friday, October 6 at 8 p.m. until Saturday, October 7 at 2 a.m. Southbound main lanes between Marbach and Valley Hi. All lanes will close while crews work on center median barrier. Traffic will exit Marbach, continue along the frontage road through Marbach Road and re-enter the highway before Valley Hi.
  • Saturday, October 7 at 2 a.m. until Monday, October 9 at 5 a.m. Northbound main lanes between US Hwy 90 and Hwy 151. All lanes will close while crews reconfigure the road. Traffic will exit US Hwy 90, continue along the frontage road through the Marbach intersection and re-enter at the next available ramp. Traffic will remain in the right lane until after Hwy 151.
During the closure of the northbound main lanes the turnarounds at Marbach will close and left turns onto or off of Marbach at I-410 will be heavily restricted by the off-duty officers controlling traffic at the intersection for the weekend. If you're looking to turn left onto Marbach off of I-410 you may want to find another way. If not you'll end up staying on the frontage road to the next available turnaround to return to the intersection. If you're in the southbound lanes that means going all the way down to Valley Hi to turn around.

The turnarounds will remain closed until the new bridge is complete spring of 2020.

This weekend’s closure allows Williams Brothers to shift traffic toward the center median over the Marbach Road overpass bridge. The Marbach Road overpass bridge is being reconstructed and widened to accommodate lanes headed to and coming from two new direct connectors being built at the intersection of I-410 and U.S. 90. A similar shift with accompanying closures on the southbound side will come October 20-23. With all lanes running in the middle of the bridge Williams Brothers will be able to reconstruct the outer portion of the bridge.

The reconstruction work starts by demolishing the outer edge of the existing bridge. Williams brother will tear out the edge of the northbound bridge October 13-16 and will wreck the edge of the southbound bridge October 27-30. Both weekends Marbach Road will close under I-410 and the frontage road on the side of the demolition activity will likely have some corresponding closures. Those details will be published in our weekly closure report.

You catch all that? Here's a little easier way to look at it:
  • October 7-9 - Full closure of northbound main lanes between US 90 and Hwy 151
  • October 13-16 - Full closure of Marbach at I-410, closure of northbound frontage road (will still have one lane open)
  • October 20-23 - Full closure of southbound main lanes between Hwy 151 and US 90
  • October 27-30 - Full closure of Marbach at I-410, closure of northbound frontage road (will still have one lane open)
Work on the $72.4 million project started January 2017 and will wrap up mid-2020.
