We have all spent countless hours stuck in traffic on the A127 over the years, but we are fast approaching the Southend Arterial Road’s centenary.

Royalty headed to south Essex for the milestone moment, with Prince Henry visiting Rayleigh to open a vital section of the road on March 25, 1925.

Crowds flocked to the roadside and the A127 was a long time coming.

Five years earlier, in 1920, Prime Minister David Lloyd George had announced plans for a programme of new roads to be built around London to create jobs for former soldiers from the First World War.

Work began on the first seven miles of the Southend Arterial Road on December 8, 1921.

Crowds and flags - more than 1,000 people line the streets to see the Prince open the road 96 years ago

By early 1924 the road was ready for final surfacing and it cost £1.5million to complete the build.
