The A370 is being closed to traffic near Brockley Stores from 9.30am to mid afternoon from 23rd to 25thJanuary to allow felling of diseased ash trees.
The diversion goes up the Brockley Coombe road, onto the A38 to Langford/Churchill then on the B3133 to Congresbury Cross junction. This is expected to add 25 minutes to journeys.
The X1 is due to take the same diversion route, with all bus stops on the A370 out of use between Congresbury Bridge and Winterstoke Road in Bristol. People in Backwell have the option of the X7.
More detailed information on the Firstbus website and on OneNetwork for a map of the diversion.
