Angry Christmas shoppers are complaining they have been stuck in a gridlocked supermarket car park for up to "an hour."
Traffic has come to a standstill at the Princes Road Tesco adjacent to the Miami roundabout, as motorists embark on Christmas food shopping.
A furious James Bell posted on Twitter: "Town is carnage, avoid Tesco at Miami roundabout total gridlock." (sp)
Twitter-user Tara said: "Tesco princes road, Chelmsford, avoid! Been sat in car park for one hour!" (sp)
While Becky McMillan added: "Tesco Can you sort out the traffic flow problem at Chelmsford? Lots of spaces but no one can leave car park, haven't moved in 30 mins!" (sp)
The problems have been repeated across Chelmsford with cars at a standstill with much of the city.
There are long delays on Springfield Road approaching Parkway, while Waterhouse Lane is also crawling.
