As a result of the Minnesota Legislature's 1996 decision to expand MSP at its present site rather than build a new airport, the Metropolitan Airports Commission has been implementing MSP 2010: Building a Better Airport. Many improvements have already been completed through the $3.1 billion program, including:

A new North/South Runway (17/35), opened in October 2005
Thirty new regional gates on new concourses A and B
Development of an award-winning dining and retail program
New airport roadways
The addition of 6,500 parking spaces at the Lindbergh Terminal and 4,700 spaces at the Humphrey Terminal. A second, 5,500-space parking ramp at the Humphrey Terminal is presently being constructed and is scheduled to open in early 2009
Twelve additional jet gates and a new food court on Concourse C
A new, 10-gate Humphrey Terminal
New auto rental facilities
A Skyway Connector linking concourses C and G, parking, auto rental, and mass transit facilities
A new transit center, providing access to mass transit buses and shuttles to off-airport auto rental companies
Parallel 1.8-mile light rail tunnels as well as an underground rail station at the Lindbergh Terminal and a surface station at the Humphrey Terminal
Two automated, climate-controlled trams: 1) an underground tram whisking people quickly from the Blue and Red parking ramps, auto rental facilities and Transit Center to the terminal and back and 2) an elevated tram transporting travelers from regional concourses A and B to the entrance to concourses C and D
Creation of children's play areas in the Humphrey Terminal and on Concourse C of the Lindbergh Terminal. The play areas were funded by the Airport Foundation - MSP, which also finances and administers the airport's Travelers Assistance and Arts and Culture programs at MSP
The switch to a more universally recognized alpha-numeric concourse and gate designation system, along with accompanying new signage
Three new airfield deicing pads to accommodate end-of-runway deicing, bringing the total number of pads to five
Runway pavement reconstruction on over 10,000 feet of 1960 vintage pavement. The middle section of both the north and south parallel runways will be reconstructed by the end of 2009.
Taxiway/apron pavement reconstruction
$110 million of vehicular roadway tunnels
Over 14 acres of stormwater ponds
