A six vehicle pile-up made traffic even more backed up on I-10 near Vado.

That area of the interstate is already slowed due to construction.

The crash happened Tuesday evening.

New Mexico State Police say a semi-truck was following too closely in the work zone, crashed and caused a chain reaction.

Seven people were injured.

One had to be airlifted to a local hospital for help, although his injuries do not appear life-threatening.
