Drivers face several more days of delays as emergency repairs continue on one road and planned work starts on another main route into Kettering.
A small section of Northfield Avenue opposite the junction with Grafton Street has been closed since Wednesday and will remain closed into the start of next week so work by Anglian Water can be carried out.
The road closure has led to delays for drivers on Northfield Avenue and the surrounding roads, particularly during the rush-hour periods.
A spokesman for Anglian Water said: “We had a burst on Wednesday and that caused quite a bit of damage to the road there.
“The pipe has been repaired and everyone is back on with their water, but we have now had to clean out the hole and start to refill it and resurface it.
“It is going to be resurfaced over the weekend hopefully.
“Hopefully it will re-open on Tuesday.”
The spokesman added that unfortunately there might be a ‘slight overlap’ with work which is due to start in Rothwell Road on Monday so the delays experienced by drivers this week look likely to continue into next week.
Rothwell Road will be closed from Monday to Friday for essential work to repair manhole covers.
Access to Kettering General Hospital will remain as usual if travelling from the west via Warren Hill, but access to the hospital from the east will be affected.
Pedestrians will still be able to access the hospital from the east side of the road as normal under the bridge.
But for those coming from the east by road, there will be delays and diversions - so a shuttle bus will be put on by Stagecoach Midlands between the town centre and the hospital.
The bus will run every 30 minutes from 5.15am to 11.15pm.
Other routes will be diverted as follows: Route 19 (Corby, Rushton, Desborough, Rothwell, Kettering, Ise Lodge) - will divert via the A43 Northern Bypass and Rockingham Road.
