Major South Texas flyover will close for hours, TxDOT warns. Here's why.

TxDOT said a key flyover at the Harlingen Interchange in South Texas was scheduled to close Thursday, June 18, for several hours so crews could complete a bridge inspection.

The temporary shutdown affected the McAllen exit to westbound I-2 from northbound I-69E, according to the Texas Department of Transportation. The closure window was set for 9 a.m. to 2 p.m.

Why the ramp closed

TxDOT said the closure was needed for a bridge inspection at the interchange, which connects I-69E and I-2 in Harlingen.

The agency said other flyovers at the interchange would remain open during the work.

Who was most affected

Drivers traveling west from lower Cameron County, including Brownsville, San Benito and South Padre Island, toward Hidalgo County were expected to feel the biggest impact.

TxDOT said the ramp closure could affect traffic headed toward McAllen and other points along I-2.

Detours posted by TxDOT

• Harrison/Tyler to West Harrison Avenue and the Lewis Lane on-ramp
• Harrison/Tyler north of the railroad crossing to Spur 54 and westbound I-2

MySA reported the advisory after TxDOT posted the closure notice the same day. The posted window was scheduled to end at 2 p.m., and the agency's guidance did not indicate any other flyovers at the interchange were closing.

Travelers in the area should check for any updates if the inspection ran longer than planned or if traffic backed up on the detours.
