Old Shoreham Road reopened to traffic today (Friday 1 June) after six months of work creating cycle lanes.
The road has been shut from The Drive and Shirley Drive crossroads to Dyke Road in two phases, most recently from The Upper Drive to Dyke Road.
There are still temporary traffic lights at two of the junctions while safer permanent crossings are installed.
The cycle paths will be formally opened on Monday 18 June during National Cycling Week.
Children at nearby schools have been playing in closed off parts of the road and teachers have been asked to remind pupils to take care now that traffic can use the whole road again.
