(KNZA)-- A Glen Carbon, Illinois woman was seriously injured in a Wednesday evening Buchanan County, Missouri construction zone accident.

The Missouri State Highway Patrol says it happened on I-29 about two miles north of Faucett around 7:30.

 The Patrol says 56-year-old Alicia Halpin was northbound when she entered the construction zone and struck an electronic arrow board sign and then an unattended pickup truck parked behind the sign.

 Her car went off the east side of the roadway and struck a guardrail. The vehicle then came back onto the roadway and traveled off the opposite side, striking a median cable.

 Halpin, who was wearing a seatbelt, was transported by ambulance to Mosaic Life Care in St. Joseph with what the Patrol described as serious injuries.
