Townfield Street car park is reopening ahead of schedule after two months of refurbishment works.
Commuters can once again park up from Monday (September 22) despite the finish date being initially pencilled in for October.
Chelmsford City Council cabinet member for safer communities Ian Grundy said: "We are very pleased with the work that has been done at the car park and to complete the work and open it up to the public ahead of schedule is a good achievement.
"The work that has now been completed will help to preserve and extend the life of the car park.
"The Council would like to thank everyone for their patience during this time and we are confident that the car park is now a much improved environment for drivers."
Work started at the end of July to install new movement joints, apply protective coatings to the decks, wells, ceilings and columns.
New bay markings were added and the internal staircase towers were redecorated.
During the works permit holders could still park on the roof but it was closed to day users.
