Reconstruction of main road 31 - Heves County
Under the leadership of the Colas subsidiary, the consortium of Colas Út Zrt. and HE-DO Kft. won the National Infrastructure Development Agency’s tender for the 11.5-tonne reinforcement of main road 31 in Heves County. The job entails various developments and reconstructions on a 23-km-long stretch of the traffic corridor.

The project is adjacent to the Jász-Nagykun-Szolnok County leg of the same road, where we have recently finished a similar reconstruction job. Colas Út has a 64% share from the six sections in Heves, which means we will have to complete works on 8 km outside, and nearly 7.5 km within built-up areas.

On sections between settlements, the technical scope prescribes pavement reinforcement, single-side pavement widening, the refurbishment of shoulders, the correction of curves, and the establishment of bus stops. In addition, we will also have to perform the relocation of telecommunication cables on a length of several kilometres.

Within the affected towns and villages, Colas is awaited by a similarly large variety of duties: besides the construction of stormwater drains and the reconstruction of the pavement structure, the assignment comprises the relocation and protection of low-voltage and public lighting power lines, and we are also to build some of the adjacent minor roads together with a number of bus pull-outs.

On 3 April 2015, we took over the work sites on all sections. In the weeks since, we have been working continuously with the help of eleven traffic light controlled lane closures and one full road closure, while tree cutting and other preparatory works have also been roaring ahead. The first week of May already saw asphalting works at some locations.
