Two crashes that blocked lanes on the Southern Motorway and State Highway 1 in Warkworth have been cleared, after causing delays during the Friday afternoon rush hour.

One crash occurred in the right northbound lane on SH1 just before the Mt Wellington Highway off-ramp.

It was cleared about 4.55pm, the transport agency said, but motorists still faced delays as traffic reduced.

Another crash occurred earlier on SH1 in Warkworth, blocking a northbound lane before Hudson Rd.

This crash had also since cleared but left heavy traffic remaining in the area, the transport authority said.
