2.4 km of connecting road

As the main contractor, M.J. Eriksson has constructed the connecting road west of Uhre, which is 2.4 km long and links Vardevej in the south with residential areas north of Vejle. The road was built in particularly hilly terrain west of Vejle, with an elevation gain of nearly 100 m over a distance of more than 1,000 m. We have constructed 2.4 km of road, two roundabouts, one two-way cycle path, one steel pipe tunnel and three large concrete wildlife crossings.

To avoid excavating in wet soil in the sloping terrain, we planned the work so that 80 per cent of the excavation was carried out between May and September, while foundation stabilisation and roadbed construction were completed in the autumn. The work included stabilising approximately 26,000 m² of soil with lime treatment. As an additional measure, around 25,000 m³ of subsoil was stabilised with lime to make it suitable for integration into the road structure. Lime stabilisation is a sustainability initiative that reduces the need for excavation and replacement of subsoil with fill or friction material.

1,200 m³ of concrete for the large wildlife crossing

A significant part of the project involved preparing for the construction of wildlife crossings, requiring the removal of more than 150,000 m³ of excess subsoil from the crossing areas. The challenging terrain added complexity to the work.

Two of the crossings have elliptical cross-sections and have a gradient of 7 per cent in the hilly landscape. For the largest passage, an intricate wooden framework was constructed, measuring 60 m in length, 25 m in width and 6.5 m in height. The wooden structure, which served as a casting mould for the concrete, was built using 600 rafters along with additional bracing and formwork.

Did you know?

It took over two months to build the formwork for the large wildlife crossing. Once completed, concrete casting began. For this passage, 1,200 m³ of concrete was used, delivered over 13 hours by 100 concrete trucks. Some 120 tonnes of reinforcement were used for the final casting.
