Special attention is being paid to the site where the almost 2km long railway bridge over river Neris will be built - it will be the longest in the Baltics.

Soil samples from more than 25m underground are being examined to determine mechanical properties and geotechnical conditions for each site.

Currently, two types of surveys are being conducted in Lithuania - geological probing along the planned mainline and more detailed geological surveys required for value engineering. The former entails drilling 10m deep boreholes every 100m to aid design decisions and prepare for future construction activities. The latter is a more in-depth analysis that will help the designers to determine what sort of foundations will be best suited for future bridges, viaducts and other structures.

Almost half of the survey work in Lithuania has been completed. Multiple teams are completing up to 15 surveys per day and a total of around 1,000 surveys for the mainline will be done by the end of November. Once the investigations are finished in the Švecarija to Šėta section, the works will continue towards the Latvian state border.
