A3 (Romania)
A3 Transylvania Motorway or Autostrada Transilvania (A3) is a motorway currently being constructed in Romania. It will be a four-lane, 588-kilometer motorway, stretching northwest from Bucharest to Oradea. The motorway will connect the cities of Bucharest, Ploieşti, Braşov, Făgăraş, Sighişoara, Târgu Mureş, Cluj-Napoca, Zalău and Oradea. The motorway will be owned by the government of Romania. Transylvania Motorway will follow almost the same route as the DN1 road (National Road 1), which became insufficient due to the growing rate of traffic between Bucharest and Transylvania.
Bucureşti-Braşov section "Snow Motorway"
The first segment, from Bucharest to Moara Vlăsiei will be built as a six-lane set of carriageways to accommodate commuting and holiday surplus traffic; the motorway will cross the Carpathian Mountains along the Prahova Valley (the Ploieşti - Braşov segment is considered the most difficult section to be built). It will also provide access to the future Terminal 2 of the Henri Coandă Airport and to the future A5 (Bucharest - Chişinău) motorway, via the Ploieşti South-East/Dumbrava interchange. Works on Bucharest - Ploieşti section of the A3 started on 15 March 2007. Works on Comarnic - Braşov, the most difficult segment of the motorway, have not started yet and should take around 4 years to complete.[1]
The total construction cost of the segment is estimated at 1.2 billion euros.[2]

Braşov-Oradea section "Transylvania motorway"
Bechtel contract controversy
This motorway segment was originally scheduled to be built by American company Bechtel Corporation together with its regional partner Enka A.S. of Turkey. The contract was awarded in 2004 to Bechtel Corporation by the Social Democrat Prime-Minister Adrian Năstase without an open bidding process, invoking "national security" as an excuse.[3] The estimated construction cost was 2.8 billion € in 2003, rose to 4.7 blillion € in a 2007 estimate.[4] Although officially the deadline is set for 2013, the final cost and finalization date are currently unknown.[5] As per Romanian ministry of transportation, Anca Boagiu, the original contract was highly disadvantageous to the Romanian side. Following the contract renegotiation[6] that occurred in June–July 2011, Bechtel agreed to lower the building cost per kilometer by 50 % down to 6.9 million euros.[7][8] Also it was decided that the American company will build only 2 segments of the A3 (Borş - Suplacu de Barcău and Gilău - Câmpia Turzii), leaving all the other segments of the motorway open for tendering.[9]
