A two-vehicle collision caused traffic problems on North Third Street near the westbound Columbia exit ramp of Route 30 on Saturday about 10 a.m. The accident involved a Volvo V70 station wagon and a Ford Freestar minivan, both of which sustained front-end damage. Northbound traffic on North Third was diverted left onto Cedar Street. Two vehicle occupants suffered minor injuries but neither was hospitalized. Emergency crews initiated spill control measures due to fluids leaking from both vehicles, which were then towed from the scene. Airbags deployed in both vehicles.
