A MAIN road into the city is closed for three weeks for major road works.

From today the A338 between the Britford Park and Ride and the Harnham Gyratory will be closed.

It will be closed until Friday, September 25 but not during weekends.

The closure is for "carriageway resurfacing and restructuring, road markings, adjustment of ironworks and associated works".

Local traffic and buses will have access via gatemen, and through traffic will be diverted via Blandford.

There have already been reports of traffic backing up in the city. 

The road was set to have been in "total gridlock" during this morning's rush hour traffic.
