Grosvenor Road
Road users are now unable to turn left from Great Victoria Street on to the Grosvenor Road.
Mr Woods explained this was a "pedestrian safety" issue as the department had to remodel the junction "to cope" with the numbers of pedestrians leaving Belfast Grand Central Station.
He noted it was under "close" review and that there were other routes onto the Westlink.
Dublin Road
When asked why the lanes on the Dublin Road were reduced from four to one, Mr Woods said some of the measures had been in place for a long period of time.
He said the cycle lane was introduced at the start of the Covid-19 pandemic to create "safe cycle routes for people".
Mr Woods added that an additional bus lane was added to the road so that if there was congestion, buses could still travel along Great Victoria Street and through Shaftesbury Square.
There is now parking, a cycle lane, bus lane and a lane for general traffic.
