The midfield terminal at DTW
had been in the works for a long time.
The initial concept came to light in the late 80's/early 90's when DTW
was looking at its long-term master plan. Pretty much after the NW
/RC merger already then, DTW
was max-ed out spacewise in its current form.
The south access road, new tower, and new crash rescue building were the first elements included in the plan and opened in 1992. The south access road was built in preparation for the new terminal and to connect to the current facilities. However, until 2002, the road basically went nowhere and ended in the middle of the airfield at the new tower. In 2000/2001 they began extending it up to the north to connect with Rogell Drive.
and Wayne County announced the new terminal formally in 1996. I believe site preparation began in 1998 or so. Actual construction in terms on concrete pouring and steel work started in 1999. The shell of the building was completed in late 2000 I believe. I remember that the steel work went up real fast. At the same time the parking deck was being built from prefab concrete sections, and the roadway was being extended to the north. Runway 4L/22R construction was also concurrent with the midfield terminal, with site work beginning in 1998.
The terminal was to open in December 2001 but was pushed back until late Feb. 2002 due to minor construction delays and also NW
wanting to wait until after the holidays to minimize the impact of transitioning facilities and wait until slower demand. The new runway opened in Dec. 2001. I remember being in the new terminal three days after it opened at it was still a work in progress. There were still contractors everywhere, a lot of construction equipment, especially out in B/C. But either way, it was a great improvement and is generally well received. The improvements currently underway will only make it better in the future.
Perhaps someone else will have better dates. I'm sure that IND
's terminal will be nowhere near the scale of the Worldgateay. (Note - I won't call it the McNamara terminal because the corrupt old dude doesn't deserve to have his name on the facility, but thats a whole other story) Plans were in the works for a while until formally announced, but site prep took about a year and actual construction was about 3 years +/-.
