As work continues to build new connector ramps between I-69 and Loop 610 in southwest Houston, a major closure is set to take place April 29.

The I-69 southbound connector ramp to Loop 610 southbound will close at 9 p.m. April 29 and will remain closed for two years, said Danny Perez, a public information officer with Texas Department of Transportation, which is managing the project.

TxDOT is also closing the I-69 southbound exit ramp to Chimney Rock Road at that same time for two months, Perez said.

Although TxDOT would typically try to keep the existing ramp open while building the new one, Perez said it will not be possible with the roadwork to come. Construction crews will need the room freed up by the closure to build the Loop 610 northbound main lane bridge over I-69, he said.

Work at the interchange is intended to improve safety and mobility, in part by widening the connector ramps to two lanes, according to TxDOT. Work previously necessitated the closure of the northbound I-69 connector ramp to northbound Loop 610, which reopened in October. A northbound Loop 610 exit ramp to Westheimer Road remains closed.

The overall project is set to finish in 2024.
