Work has begun on a pilot scheme to build the first section of a dedicated High Occupancy Vehicle (HOV) lane on a UK motorway.

The 1.7mile (2.75 km) lane will link the southbound M606 near Bradford to the eastbound M62 towards Leeds allowing vehicles heading towards Leeds with more than one occupant to bypass traffic at the busy Chain Bar junction.

It is estimated the £3.95 million pilot could reduce peak time journeys for those sharing their car at the site by around eight minutes. Studies show that up to 84% of vehicles using the junction currently have only one occupant.

The new lane is expected to open in the spring.

The new lane will use the hard shoulders of the existing M606 and M62 eastbound slip road, which will be connected by a short stretch of new carriageway next to Chain Bar roundabout. New lay-by areas will be provided as emergency refuge for broken-down vehicles in place of the hard shoulder.

Vehicles that can use the HOV lane on the M606 are cars with two or more people in them - including when towing a trailer or caravan - coaches, buses and motorcycles. Minibuses and taxis can only use the lane when carrying passengers. HGVs will not be allowed to use the HOV Lane.
