Masshouse Circus was a junction on the Queensway, Birmingham's inner ring road. The junction was originally constructed in the 1960s, along with much of the inner ring road, which at the time was numbered A4400, Masshouse was a grade separated roundabout with the A47.
As part of a scheme to remove the "concrete collar" from the city centre, the junction was completely removed in March 2002 at a cost of £24.2 million and replaced by an at grade network of roads, including a gyatory slightly to the east of where the junction once stood. Part of the old underpass is still visible on the site, which is now used as a car park, awaiting further redevelopment.
The Birmingham branch of Friends of the Earth happily sold off chunks of rubble from the junction for the princely sum of 50p.
