Overtaking lanes are wide single carriageways marked out as two lanes in one direction and one lane in the other with opposing traffic streams separated by a double white line system. They provide defined overtaking opportunities to reduce traffic delays caused by slower moving vehicles.
The Regional Strategic Transport Network Transport Plan 2015 envisaged the construction of over fifty 2+1 overtaking opportunities within the plan period. The following are some of the completed schemes.
