New roundabouts on the 31 motorway to be completed soon

Two important junctions will also have roundabouts on Pest County's busy main road. As the legal successor to NIF, the Építési és Közlekedési Minisztérium investment will be implemented by KM Építő Kft..

• a four-lane roundabout will be built in Nagykata at the intersection of main road 31 and main road 311, at the intersection of Jászberényi út and Kossuth Lajos utca, which will result in easier and safer passage for the passing traffic.
• A three-way roundabout will make traffic more dynamic in Sülysápon at the junction of main road 31 and road 3105, at the junction of Pesti út-Fő utca-Szent István tér.

The Nagykápa project has a net value of nearly HUF 350 million, while the Sülysápa project is worth more than HUF 600 million. Both investments are financed from domestic sources.

The projects aim to improve the safety and traffic dynamics of the highway 31 intersections, which are at risk of accidents due to increased passenger and freight traffic and inadequate geometric designs.

Traffic engineering and landscaping already underway

Both roundabouts are located in the vicinity of a densely built-up inner-city area, and despite the site constraints, they will be designed as three- and four-lane roundabouts that are fully adapted to the changed traffic load. The roundabouts will have a radius of 17.5 metres and a width of 5.5 metres. Pedestrian traffic will be served by a wide pedestrian walkway and pedestrian crossings across the islands separating the roundabout branches.

Due to the reconstruction of the nodes and the changed track routing, it is necessary to convert the existing variable transformer stations to a single compact transformer station and to replace the 20 kV supply lines of the transformer stations with underground cables. The replacement of the low-voltage overhead line network and its connecting lines, as well as the rebuilding and extension of communication lines and street lighting installations are also part of the projects.

As part of the finishing works, the final traffic engineering, landscaping and grassing of the green areas are being carried out by KM Építő Kft.. The technical handover is expected to be completed by the end of June 2023.
