IN Brief:
- Balfour Beatty has completed Station Road bridge piling on the North Hykeham Relief Road.
- River Witham piling, ground improvement, earthworks, drainage, and bridge structures continue during November.
- The programme includes temporary traffic management through January 2027 and a planned summer 2029 completion.
Balfour Beatty has completed piling at the Station Road bridge on Lincolnshire’s North Hykeham Relief Road, while foundations and ground improvement works continue around the River Witham. The November construction programme moves into reinforced concrete structures at Station Road and the Wath Lane accommodation bridge, alongside major earthworks, drainage installation, and utility diversions. The council’s latest progress record marks a shift from site establishment and preparatory piling towards the construction of permanent bridge elements.
The five-mile relief road will run between the A46 Pennells Roundabout and the A15 Sleaford Road, completing a strategic highway connection around Greater Lincoln. Construction began in March 2026 after the necessary approvals and enabling work. The project combines a new carriageway with bridges, junctions, earthworks, drainage infrastructure, and connections into existing roads. Lincolnshire County Council is overseeing the scheme, with Balfour Beatty carrying out the principal design and construction contract.
At Station Road, the completed piles have been cropped to their specified cut-off level and construction has begun on the structure above. Cropping removes the surplus concrete at the pile head and allows foundation elements to connect with the reinforced concrete structure. That work transfers the programme from installing below-ground support to building permanent bridge components. Lincolnshire County Council identifies the piling as complete and the superstructure works as under way; the bridge itself remains under construction.
Around the River Witham, piling began in October and ground improvement continues to the west of the watercourse. The sequence prepares the bridge foundations and adjacent earthworks, which need to accommodate local ground conditions and the interfaces with water management. A temporary crossing installed earlier in the programme is already carrying construction traffic between work areas. That route supports the movement of personnel, materials, and plant while the permanent bridge foundations are developed.
The November programme includes further piling across the scheme, continued construction of the reinforced concrete structures at Station Road and Wath Lane, and excavation around Lincoln Cliff. Bulk excavation and embankment construction establish the levels and geometry required for the new carriageway and associated structures. Material recovered near Grantham Road is being processed for reuse elsewhere on the route, reducing the need to transport suitable excavated material out of the project before importing replacements.
Earlier stages included mobile crushing of material excavated from Lincoln Cliff for reuse in the road’s embankments and associated works. A dedicated construction haul road is intended to remove more than 150,000 vehicle movements from surrounding local roads over the life of the scheme, according to the project’s estimate. Reusing suitable material reduces off-site disposal and imported aggregate requirements, while the internal haul route carries large loads between excavation and placement areas. Both measures support the earthworks programme across the five-mile alignment.
Permanent drainage is progressing in parallel with the highway and structural works. Contractors have excavated attenuation ponds and ditches, installed piped culverts, and continued pipework and headwall construction. Attenuation storage moderates the flow of stormwater discharged from the new road, while culverts carry water beneath embankments or access routes. The permanent systems must be integrated with temporary measures that control water and sediment as exposed earthworks are excavated and placed.
Utilities provide another constraint on construction sequencing. Diversions continue on Station Road and Brant Road, with further Anglian Water work planned on the A607 Grantham Road from 16 November. Temporary signals are expected for up to one month. Approaches to the A46 Pennells Roundabout also face a single-lane closure during vegetation clearance in the week beginning 2 November. These operations create space for future highway structures and connections but require coordination with existing traffic and underground services.
From 4 January 2027, an inbound-only closure of Newark Road towards Lincoln is planned for up to seven weeks at the A46/A1434 Pennells Roundabout. Traffic leaving Lincoln will continue outbound, while inbound vehicles will be diverted using the A46 northbound and the A57/Saxilby Road. These arrangements support construction of the connection between the new relief road and existing highways. Temporary restrictions on public rights of way, live plant crossings, and lower speeds at several work areas will also remain while civil engineering continues.
The project is supported by a £110m Department for Transport allocation under the Large Local Majors programme, with the balance of funding coming from Lincolnshire County Council and developer contributions. The route is intended to divert traffic from the urban network and improve journey reliability. The council also identifies potential capacity for approximately 4,500 homes and seven hectares of employment land, together with an estimated £800m of economic benefits over 60 years; those are projected outcomes, not benefits already delivered.
The relief road remains programmed for completion in summer 2029, subject to the council’s stated timetable conditions. The immediate engineering sequence links foundations and concrete bridge structures to the surrounding earthworks and drainage, while utility diversions clear the interfaces with existing roads. The route can then progress through formation, surfacing, and its eventual junction connections. In the shorter term, the planned January 2027 Newark Road restriction marks a specific next stage in tying the new road into the existing highway network.
