The main objective of the project is to build the second track of the corridor IXB and to divert the train traffic from the Vilnius City centre. A consortium of companies under the management of Kauno tiltai AB will have to finish reconstruction works within 33 months. After reconstruction the freight trains will be able to travel along the bypass which will be 24-km long at a speed of up to 80 km per hour.

During the second stage of reconstruction of the Jakai roundabout a 317-metre long overpass in the Kaunas-Palanga direction and a 552 metre-long overpass in the Palanga-Kaunas direction was built. Both overpasses has two traffic lanes in both directions. Their total length - 869 metres. »

35 kilometres of track will be reconstructed in the Radviliškis - Pagėgiai railway section. It is planned to lay new rails, to correct the width of railway bed in some places, to partially rearrange drainage and crossings, to install water channels, to repair the existing and to install the new aprons and pedestrian crossings, to reconstruct culverts and the lighting system.

During repairs the bridge was widened up to 14.6 metres (instead of the former 9 metres). A new bridge was built and the span structure of the old one was demolished, the bridge was provided with a sidewalk and a bicycle path. The works were implemented without closing of traffic.

During reconstruction of the Vilnius Lazdynai Bridge, street illumination and a trolleybus contact line was installed. The bridge was widened up to eight lanes, instead of the former six. A section of Oslas St. from the Lazdynai Bridge to Erfurtas St. was repaired, and a viaduct on Oslas St- Laivės Ave. was renovated.

During the project 28.247 km of railway was constructed, and the existing railway was reconstructed. Switches were replaced by new ones with reinforced concrete sleepers or relaid on reinforced sleepers. Unnecessary tracks interfering with the development of the railway network were removed. Drainage, automation, communication and power supply systems were installed.

The frame bridge to Nemunas River Island is 155-metres in length and 14.6-metres in width. Abutments have been built on reinforced concrete pole foundations. Intermediate steel concrete bearings were fixed firmly in the monolithic reinforced concrete grillage and the span structure. The span structure is a reinforced concrete monolithic hollow slab with transverse diaphragms at the abutments and intermediate bearings.

During reconstruction the bridge was widened up to eight traffic lanes and integrated into the network of western and eastern access street network. Engineering networks, lighting and a trolleybus contact line were also reconstructed; Oslo St. was reconstructed between the Lazdynai Bridge and Erfurto St., and the viaduct across Oslo St. – Laisvės Ave. was renovated. »

During reconstruction of the Jakai roundabout, a four-lane scaffold bridge, the longest in Lithuania – 610-metres – was built. It was awarded a gold medal at the contest Product of the Year 2010. The width of the scaffold bridge ranges from 20 to 30.5 meters, Also, a tunnel viaduct was renewed, engineering networks were reconstructed, and lighting of the scaffold bridge was installed.

The reinforced concrete railway bridges were reconstructed. The works were carried out without closing the train traffic, i.e. during the breaks of traffic. The railway track was disassembled: the grate was removed and the ballast was discharged. The span structure was dismantled, the existing ballast was removed. A metal culvert was installed which was covered with sandy soil. A layer of crushed granite ballast was also laid and a new grate was built. Also, the finishing works were carried out.
