Police say two people were injured and traffic delays were building as a result of a serious motor vehicle crash on Route 9 north in Woodbrige Thursday afternoon.

According to the Woodbridge Police Department, the crash was reported at 4:46 p.m. as the peak of rush hour traffic approached on the busy roadway. Police say two vehicles were involved in the crash, and two victims were transported to local medical centers, one by medivac helicopter, which landed on the roadway. The extent of their injuries is not yet known, authorities said.

As emergency crews worked to investigate the crash and clear the wreck, police said only one lane of traffic was in use, causing delays. Authorities did not have an estimate as to how long the backups were expected to last.

Authorities say the crash is still under investigation.
