TPF Sp. z o.o. implements for Voievoidship Roads Administration in Olsztyn, the following service: performs functions of an Engineer over the implementation of the Extension of the voievoidship road 507 Braniewo - Pieniężno project separated into two tasks. Task 1: the extension of the voievoidship road 507 Braniewo - Pieniężno, and Task 2: the extension of the voievoidship road 507 Braniewo - Pieniężno at Wola Lipowska-Pieniężno section.

The extension of the road consists of the section km 0+000,00 to km 14+960,00 of about 14,575km total length, which is a part of stage I of DW 507 Braniewo-Pieniężno and 13,880 km length extension from km 14+960 to km 28+840,80, which is a part of stage II of DW 507 Braniewo-Pieniężno extension. The start of the road 0+000 consists of the intersection with national road 54, which leads to the border crossing with Rosją Gronowo - Mamonowo. At km 7+770 the road intersects with the express road S22 from Elbląg in the direction to Kaliningrad. The section of the voievoidship road 507 from km 6+898 to km 7+283 (the area of the interchange) was excluded from the extension plan, as the road at the above section had been already reconstructed. The major part of the designed road system coincides with the existing road 507 section. From km 26+600 it is planned to change the course of the road - the bypass of Pieniężno, which will end joining the existing road 510 in the area of the intersection with Królewiecka street. DW 507 road is an important transport link at Warmian-Masurian Voivodeship area.
