Staples Corner

From Wikipedia, the free encyclopedia

Staples Corner is a major road junction in London, United Kingdom, with two linked roundabouts and flyovers, which connects the A406 North Circular Road with the A5 Edgware Road and the start of the M1 motorway. Also running through the Staples Corner, between the two roundabouts, is the Midland Main Line & Thameslink railway line.

Staples Corner is named after the Staples Mattress Factory. Mr. Harold Heal commissioned the designing and building of the factory which was located on the road junction from 1926 to 1986.

The Staples Corner junction was built in accordance with plans from the 1960s to continue the M1 further south to West Hampstead. These proposals, part of the London Ringways Plan, would have seen seen a three level junction with the M1 as the middle level crossing above the roundabout on a flyover and passing under the A406 flyover. South of the junction the motorway would have headed through Cricklewood on an elevated roadway to meet the North Cross Route section of the London Motorway Box (Ringway 1) at an elevated Y-shaped junction. Most of the Ringways Plan including the North Cross Route was cancelled in 1973.

On 11 April 1992. an IRA bomb went off underneath the A406 flyover, causing serious damage to roads and nearby buildings and causing the closure of the junction. Another bomb went off near the junction in 8 October 1993, causing damage but no injuries.

The B&Q DIY store damaged by the bomb was replaced by a branch of the appropriately named Staples office supplies. There is a large retail park at Staples Corner, located between the A5 and the railway line. Close by is the Brent Cross Shopping Centre, named after the A406 and A41 road junction.

The format of the Staples Corner junction was modified during the reconstruction works necessitated by the bombings. An additional sliproad onto the M1 from the east was added to remove the need for traffic coming from that direction to travel around the roundabout to access the motorway.
