IMAGES show the work which has been undertaken at the Frocester Hill junction.
The work, focussing on Frocester Hill and the junction with the B4066, consists of new road markings and signs, in response to police collision records and concerns from the local community.
The signs include reminders to motorists about the speed limit and to give way, as well as warnings over bends in the road to be aware of.
Existing road markings, including centre lines and reminders to drivers to slow down, were also refreshed to make them more visible and prominent.
There was a road closure in place from April 3 to 13, with the work now completed ahead of schedule.
"Works have completed ahead of schedule and improvements look great," read the post from Gloucestershire Roads.
"The crew thank you for your patience and cooperation."
Cllr Dave Norman, cabinet member for road safety, previously said:“We are pleased to be able to carry out these improvements at Frocester Hill, in line with our commitment to improve road safety in Gloucestershire.
