A trackhoe being carried on the back of a semi truck trailer was knocked off the trailer after hitting the I-15 Proctor Lane overpass in Lindon. The bridge is actually scheduled to come down Saturday December 18th, as part of the I-15 corridor construction project.

LINDON — An oversized load was a bit too oversized for a bridge over I-15 in Utah County. A track-hoe that was riding on a trailer struck the Proctor Lane overpass as it moved under the bridge on southbound I-15, near milepost 275 Tuesday morning.

The bridge was set for demolition Saturday as part of the massive I-15 Core construction project. A new bridge is being built just to the north and UDOT had planned to shift traffic onto that bridge by the weekend.

UDOT spokesman Scott Thompson said the bridge, which has a posted clearance of 15 feet, 4 inches, has not been a problem for high loads. "Most of the bridges we are putting back in place are about 16-17 feet high, so it will be higher," he said.

Highway Patrol Trooper Janet Miller said the load measured 16 feet, 2 inches.
