A road is to be closed for 15 weeks so a railway bridge can be rebuilt as part of a £70m scheme to speed up train journey times.
Finedon Station Road bridge will close temporarily to all road traffic from Monday, June 17, to Monday, September 30, 2013.
Access from the east to properties in Finedon Station Road and Furnace Lane will be maintained throughout.
Diversion routes have been agreed with Northamptonshire County Council and motorists are being advised to use the A5128 (Finedon Road)/A510 (Wellingborough Road) to cross the railway.
The heavy goods vehicle ban on part of Finedon Road and Station Road will be lifted temporarily.
The northern approach to Burton Latimer via A14/A6 roundabout is unaffected.
Once complete, the new bridge will provide the extra headroom needed for trains to travel at higher speed, as the forces involved mean trains tilt to one side as they pass through curved sections of track.
Network Rail acting route managing director Justin Page said: “This work will deliver quicker journeys for the ever-growing number of passengers on the Midland Main Line, helping to bring the region’s biggest economies closer together.
“Our longer-term plans to upgrade and electrify the line will transform our diesel railway into one of the most modern in Europe providing more seats, even faster journeys, and cleaner and quieter trains.
“We thank people in advance for their patience and will continue to work closely with Northamptonshire County Council and Kettering Council as we continue our plans to build a better railway for the East Midlands.”
