Loop 1604 on Northeast Side reopens after 18-wheeler crashes over bridge wall

Westbound lanes of the highway were closed on Wednesday

SAN ANTONIOUpdate (Wednesday, 4:20 p.m.)

A multi-vehicle crash on a portion of Loop 1604 led to an 18-wheeler hanging over a bridge wall and an hours-long road closure.

The crash happened Wednesday afternoon on the Green Mountain Road bridge above Loop 1604 on the Northeast Side.

According to a crash report from San Antonio police, the driver of the 18-wheeler was heading westbound in the 700 block of NW Loop 410 before the crash.

While the truck was en route, a blue Honda Civic side-swiped a red Dodge Charger while trying to change lanes, causing the Charger to spin out in front of the 18-wheeler, police said.

The 18-wheeler slammed on his brakes but told police he was unable to stop in time and t-boned the blue Honda, the report states.

Due to the semi-truck’s abrupt stop, the straps holding down its load snapped, causing the pallets of bricks to scatter on the highway, SAPD said.

The 18-wheeler also hit a traffic sign, and the two other vehicles involved in the crash were unable to avoid hitting it. No injuries were reported.

As of 4:20 p.m., police said the crash scene was still active, and the westbound lanes of that portion of Loop 1604 are still closed off. However, the eastbound lanes were reopened.

It’s unknown if any charges will result from the crash.

We’ll bring more updates to this story as they become available.
