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). Staygate roundabout is very close to
Odsal Stadium, the home of the
rugby league club
Bradford Bulls. . 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 complex traffic-light controlled roundabout. 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 lane scheme was on the M606 southbound and allowed vehicles with more than one person in the car a fast track onto the
M62 eastbound at Junction 26. In August 2017 the lane's restriction was removed and is now open to all traffic. In September 2016, it was revealed that the M606 is the slowest part of the motorway network averaging . ==List of junctions==
