DALLAS (CBSDFW.COM) — One person was killed and three injured Thursday when a bridge currently under construction was hit and collapsed onto Interstate-35 in Salado, Texas.

CBS 11 has confirmed the man who died was a 32-year-old man from Arlington. At this time, nothing more is known about his identity.

The accident was reported at 11:15 a.m. at FM 2484 and I-35.

According to TXDOT, an oversized tractor trailer struck a bridge support, causing several beams to fall onto the roadway.

Nick Delgado with CBS affiliate KWTX says a pickup truck appears to be buried beneath the pillars.

“There is a mountain of concrete. There’s debris that came out of the back of one of the 18-wheelers just all over,” said Delgado.

A construction company is currently using a crane to move debris on the roadway to search for additional victims.

The three patients were transported to Baylor Scott & White Hillcrest Medical Center in Waco in unknown conditions. Their injuries are not believed to be life threatening.

Bell Co Sheriff Lt. Donnie Adams says traffic on I-35 is stopped in both directions and is being directed to the service roads.

TxDOT is encouraging motorists to seek alternative routes, such as SH 95 between Temple and Georgetown; US 190 from Belton to Killeen; and 195 to Georgetown.

The roadway is expected to remain closed until at least nightfall.
