Contractors for Highways England have been working around the clock to replace the bridge joint on both sides of the carriageway.
Work started on Monday 5 September and was due to be completed by the end of October but the contraflow which is currently on the southbound carriageway will be removed this weekend.
In order to remove the contraflow the A19 southbound carriageway will be closed between the A67 at Crathorne and the A174 Parkway junction overnight on Sunday between 8pm and 6am.
Highways England project manager Phil Leng said:
This is fantastic news for drivers that the work has been completed 2 weeks ahead of schedule. This Sunday evening we will need to close the A19 southbound carriageway so the contraflow can be removed. And from 6am on Monday the speed limit will be returned to normal.
For the last six weeks our contractors have been carrying out essential maintenance works to the bridge joints which will prolong the life of the bridge.
Clearly signed diversions will be in place for drivers using the southbound carriageway.
