Heads-up, Northeast Side drivers: TxDOT is shutting down two ramps at the I‑35/I‑410 South interchange this weekend for bridge work, a move that will send traffic on a brief detour dance and likely slow your roll. The closures hit the southbound I‑35 connector ramp to southbound I‑410 South and the southbound I‑35 frontage‑road entrance ramp to I‑410 South. Work starts early Saturday and runs through Sunday evening, so pack a little patience.
🚧WEEKEND CLOSURE🚧 The southbound I-35 connector ramp to southbound I-410 South and the southbound I-35 frontage road entrance ramp to southbound I-410 South will be closed for bridge work. The closure is scheduled from 6 a.m. Saturday, 11/15, until 9 p.m. Sunday, 11/16.

Detours and what to expect
Drivers who typically use the closed ramps will be routed onto surface streets and frontage roads. Follow posted detours directing you to George Beach Avenue and the northbound I‑35 frontage road before rejoining the I‑410 South frontage road, according to TxDOT. The agency also notes the connector from southbound I‑35 mainlanes to I‑410 South is expected to remain open while the frontage‑road entrance is shut. Expect flaggers, equipment, and some extra merge drama near the interchange during work hours.
Part of the I‑35 NEX expansion
This weekend’s work is tied to the multiyear I‑35 NEX program to add elevated lanes and new direct connectors at the I‑410 interchange, outlined by TxDOT. Local coverage has repeatedly flagged the drumbeat of overnight and weekend closures as crews set beams and pour bridge decks to speed construction while easing weekday disruption, as noted by Express‑News.
When to watch for delays
According to TxDOT San Antonio, the closures run from 6 a.m. Saturday, Nov. 15, until 9 p.m. Sunday, Nov. 16, weather permitting. Expect heavier-than-normal traffic on nearby frontage roads and at the George Beach Avenue turnaround during the window.
