A growing number of US airports are planning to build rail links that connect passengers directly to rail systems in order to reduce surrounding road traffic.
Seattle-Tacoma and Dallas Love Field International airports anticipate opening direct rail connections later in 2009, USA Today reports.
New England Transportation Institute director Matthew Coogan said that there was an overall consensus in this strategy to deal with ground transportation challenges.
The Salt Lake City, Phoenix Sky Harbor, Miami, Dallas / Fort Worth and Oakland airports have also approved rail projects, which will be complete in the next few years.
Denver, Washington Dulles and Los Angeles airports are also sketching out similar projects.
