A LANE of Felix Street in Brisbane's CBD remains cordoned off after a sinkhole appeared late yesterday.

A Brisbane City Council spokeswoman said crews placed a temporary patch of road base and asphalt over the sinkhole about 2am today but now had to wait until the pipes and drains underneath the road had been identified before carrying out further repairs.

"Council is doing the responsible thing and is dialling before they dig," she said.

The left lane of Felix Street will remain closed until further notice, with drivers advised to avoid the area.

It will not be re-opened until the cause of the cave-in can be established.

The sinkhole is the width of the lane and appeared in the middle of the road on the corner of Margaret and Felix streets yesterday afternoon.

It is believed the damage could be the result of recent flooding in the area.

Access to Felix Street and Margaret Street beyond Edward Street is restricted to the right lane only.
