J1 → M62 motorway
The M606 is a short stretch of motorway in West Yorkshire, England. Called the Bradford Spur motorway, the M606 leaves the M62 motorway at junction 26, near Cleckheaton, and heads into Bradford, to join the A6177 Bradford Ring Road. It is officially named the "Bradford South Radial Motorway" and was opened in 1973.
Configuration of the terminal junctions
The northern end of the M606, closest to the city, was built with a large raised roundabout crossing the Bradford Ring Road, but the original plans to continue the motorway under the roundabout were not carried out: access was only by slip roads to and from the roundabout.
In 1999 a new slip road was built that allowed eastward traffic on the ring road, via a mini-roundabout, to enter the motorway directly and avoid the Staygate roundabout.
In 2004 the junction was further remodelled, so that traffic leaving the motorway and wishing to turn eastward on the ring road continues under the roundabout, and round to join the roundabout from the opposite site, so that it has a left rather than a right turn to make (via two sets of traffic lights).
The southerly junction with the M62 is known as the Chain Bar Interchange and features free-flowing sliproads from the Manchester direction M62 traffic to Bradford, but not the Leeds direction, which has to use the complexed traffic-light controlled roundabout. Since late 2007 there is a 2+ lane leading from the M606 straight on to the M62 without having to stop at Chain Bar Interchange.

Britain's first dedicated motorway carpool lane
In 2007, work started on the M606 to create the UK's first motorway carpool lane (also known as high-occupancy vehicle or HOV lane). The 1-mile (1.6 km) lane scheme is on the M606 southbound and will allow vehicles with more than one person in the car a fast track onto the M62 eastbound at Junction 26. 
In September 2016, it was revealed that the M606 is the slowest part of the motorway network. Drivers crawl along at an average of 24.6 miles per hour (39.6 km/h).
