Drivers headed into the city were slogged with half-hour delays as one lane in each direction of the Story Bridge were closed.

Police shut down the inner lanes of the bridge about 8:40am on Thursday, but these have since been reopened.

A police spokeswoman said a motorcycle and car were involved in a crash and sustained injuries but these did not appear to be life threatening.

Australian Traffic Network's Jaylan Yilmaz said drivers that headed along Main Street towards the bridge were expected to have an extra 30 minutes added to their trip.

Drivers headed to the Story Bridge from Wynnum Road faced 40-minute delays, he said.

By 10am, traffic had cleared up around the bridge, Mr Yilmaz said.
