If you rely on the eastbound Loop 1604 entrance ramp right after the I-10 interchange near The Rim, your routine is about to change for good. TxDOT will permanently close that ramp on Monday, July 6, 2026, starting at 9 a.m. The closure is part of ongoing work at the busy I-10 and Loop 1604 interchange, with a new entrance ramp to Vance Jackson Road scheduled to open at the same time. Drivers who usually shoot up the old ramp should plan for a new route and some extra congestion while crews shuffle traffic patterns.
What drivers need to know
In a recent update, TxDOT said the eastbound entrance ramp immediately after the I-10 interchange will be shut permanently and that motorists on the eastbound frontage road will need to continue to the next available entrance ramp to reach the mainlanes, as reported by MySA. The agency says closing the ramp now lets crews finish the current round of ramp reconfiguration while the new Vance Jackson entrance comes online. Commuters can expect temporary lane shifts on the frontage roads and slower traffic through the northwest side as construction keeps rolling.
Project scale and timeline
The ramp shutdown is one small piece of the Loop 1604 North Expansion, a $1.4 billion, 23-mile program that will widen the roadway, add HOV lanes and rebuild major interchanges in six segments, according to the project page at the Texas Department of Transportation. TxDOT lists the overall project timeline stretching into 2028, with the I-10 and Loop 1604 interchange being rebuilt and multiple flyover connectors opening in phases. Officials say the long game is to cut chronic congestion and improve safety at one of San Antonio's most notorious traffic knots.
Detours and short-term traffic plans
TxDOT has advised that drivers on the eastbound frontage road who want to reach the mainlanes should simply stay on the frontage road and use the next entrance ramp, per reporting from MySA. Local reporting and earlier closure notices show TxDOT leaning on frontage-road detours and tightly timed overnight work to set girders and move heavy equipment while avoiding full-day shutdowns whenever possible. Drivers should be ready for traffic control at key intersections and intermittent lane closures as crews finish the new connectors and adjust the surrounding ramps.
What to watch next
Recent milestone openings, including the latest flyover connectors at the I-10 and Loop 1604 interchange, mark steady progress in swapping out the old cloverleaf for a multi-level stack, local coverage shows. For the latest closure notices and detour details, drivers are urged to check the TxDOT project page and the agency's San Antonio social feeds before heading into the area and to budget extra travel time on the northwest side.
