Sections
36
Length
649 km
Median slip
+22 mo
Median overrun
+33.4%

Slip measured on 9 of 36 sections built.

Only construction counts toward these figures. A design contract is listed on the firm's page and never folded in, because a construction overrun belongs to whoever built the thing.

Joint ventures worked through

  • FCC Construcción – PORR Bau
  • FCC Construcción – Porr
  • Maritsa Highway consortium
  • PORR – Gülermak – Energopol-Szczecin JV
  • PVT-M0 Konzorcium

Work done in a joint venture is credited to each member firm, so a venture has no page of its own and never appears beside its members: that would count one section twice.
