Construction continues this spring on major Grand Parkway connectors

Much of the construction focus will be on the Hwy. 290 interchange in the first quarter of the year, Merritt said, with some frontage road closures necessary and limited main lane closures on nights and weekends.

It is unknown when beams will be placed over I-45 main lanes, however Merritt said that portion of the project would be completed between 8 p.m. and 6 a.m. to avoid peak traffic times. There has already been some reduction of main lanes at night and some frontage road closures, she said.

"Especially at I-45—which is a major artery—it is absolutely a goal [to have] as little impact to traffic as possible," Merritt said. "While there will be some reduction of lanes, it will take place at night."

The date for the completion of the I-45 interchange is unknown, but all three segments of the project—F-1 from Hwy. 290 to Hwy. 249, F-2 from Hwy. 249 to I-45, and G from I-45 to Hwy. 59—will open concurrently sometime late in 2015, Merritt said. All 38 miles will be an electronically monitored tollway that motorists can pass through using state-issued toll tags. She said the Harris County Tollroad Authority would set the toll rates, which will be consistent with Sam Houston Parkway.

Construction could affect areas along Riley Fuzzel Road. Merritt said Riley Fuzzel will align with Hwy. 99, as the existing road will become the westbound frontage road for the Grand Parkway.

Right-of-way negotiations continue for the project, and no timetable has been finalized for construction in the area, Merrit said.

"Ultimately, there will be a phased schedule to lessen the impact," she said.
