Two separate incidents caused disruption on the city's roads this morning.
Bus services were being diverted after an accident in Horsforth, which partially blocked the road at the Southway junction.
West Yorkshire Metro said the SM7, SM2, SM5 and 97 services were all affected.
The road has now reopened.
Meanwhile, disruption was being reported in Holbeck where fallen roof tiles led to the closure of part of Whitehall Road.
