Repair work is being planned for a bridge at Alfreton’s Watchorn Roundabout, almost nine months after it was damaged by a lorry.
The lorry, which was carrying a digger, struck the bridge above the A38 dual carriageway in January.
Following an initial full closure, one of the two lanes around the roundabout has remained closed while plans have been developed to repair the damage.
National Highways previously said the work would take time to plan and deliver because of the extent of the damage.
Further work is now being planned which could allow both lanes to reopen ahead of a full repair.
A timetable for the work has not yet been confirmed, although Derbyshire County Council has listed roadworks at Watchorn Roundabout on:
- 5-6 October
- 2-3 November
- 7-8 December
National Highways said the lorry strike caused significant damage to the bridge and that repairs are complex.
The organisation said single-lane traffic had remained in place for safety reasons while plans for the repair were developed.
Some strengthening work is expected to take place in the coming months, which National Highways said would allow two lanes of traffic to operate again until the full repair is completed.
