New Haven International (NHX) is the chief airport of the capital of Calderwood, New Haven, near the town of Carmonforth, NE of New Haven. It was built in 2003, replacing the smaller airport south of the city which now deals with mostly cargo and commuter flights.

Construction

The airport was built in five phases of construction.

Phase 1

In phase 1 the ground was prepared for the airport. The site chosen was near Blackford Hill, and the gorund was undulated. The entire site was cordoned off and levelled to a height of 5m above sea-level. This was done using several terrain levelling techniques including vibro-compaction, in which the ground is vibrated until all the soil particles collapse into each other, levelling the ground and also making it very stable and strong.

Phase 2

In this phase, initial access to the airport was taken into account. This included the re-routing of the M8 City Orbital closer to the airport, and the construction of Junction 14, a now notorious traffic junction. The A4 was also sunken into the ground at the end of what would become runways 36-18 L and 36-18 R. Also, the three main terminals of the airport would be cut off from the A4 by runway 13-31, and enclosed on either side by 36-18 L and 360-18 R. It was therefore necessary to construct an access road all the way around the airport site and into the terminal area from the north, or to tunnel under the airport site and into the terminal area, the latter was chosen.

Phase 3

The third and midway point in the point was the arduous task of laying and tarmacking the runways, taxiways and aprons. They were marked out with over 100 miles of rope guide fencing and it took around 8 months to complete this stage, towards the end the vehicles were working twenty four hours a day to have the phase completed in time.

Phase 4

Phase four was the construction of all airport structures. Terminals one and two are almost identical in design, a glass box with undulating roof functions as the entrance and check-in zone, with two "arms" on either side with curved ends acting as the concourses on which the planes dock. Terminal 3 is somewhat different. It is simply long with a curved roof, the check-in and entrance is integrated into the length of it, meaning it is the same width all the way along it's length. The cargo buildings are simple low lying box buildings with a modern metallic design.

Phase 5

The final stage of construction was a relief for much of the team, and was not as arduous as the other stages. It involved the final connection of later transportation access and moving all the airport equipment that could be re-used from the site on almost the opposite side of the city. This latter task was all done during one night in July, when all the airport vehicles were driven around the city bypass at 30mph to the new site. A new rail link which had not previously existed at the previous site was added, creating a new rail service from the city centre to the airport.
