“There are days we may be using barrels to shift traffic, or we may completely reconfigure lanes, and this is where it is important that motorists slow down, stay off the phones and pay attention to signage,” TxDOT spokesperson Danny Perez said.
The most significant closure to come will be the Westheimer Road ramp onto Loop 610 South, which will be shut down Jan. 10 for four to five months while crews drill a new foundation for a future ramp support. Traffic will be rerouted to Post Oak Boulevard under I-69 toward the next on-ramp for Loop 610.
Other milestones in 2020 include finishing the I-69 south frontage road between the Loop and South Rice Avenue. Work along the I-69 north frontage road between the Loop and Newcastle Drive, including reconstructing the Newcastle intersection, will get underway in early 2020 as well.
Commuters will not see any major ramps go offline until the next year, Perez said, when I-69 northbound to I-610 North will go offline for six months starting in late 2021.
When the $259 million project is totally completed in 2024, the interchange between I-69 and Loop 610 will have new two-lane connector ramps, new shoulder lanes, and other updates to improve safety and reduce congestion, officials said. Work on the project began in 2017.
