STAMFORD, CT-Following a ribbon cutting ceremony Friday, the Fairfield Metro railroad station opened to commuters Monday. It’s the first new station to open on the New Haven line in 100 years and serves as the centerpiece of Blackrock Realty LLC’s 35-acre Fairfield Metro Center.

According to the Connecticut Department of Transportation, the New Haven Line is “the busiest single rail line in the United States,” carrying 37.3 million people in 2010.

“This project will be an enormous advantage for Connecticut commuters— and state and local leaders should be congratulated for their efforts here,” Connecticut Governor Dannel Malloy said in a prepared statement. “I have been clear that we need to continue to invest in our transit infrastructure—it is one way we strengthen our economy and improve regional competitiveness. This new station demonstrates the power of partnerships to benefit the town and the state.”

In addition to the $90 million rail station, Fairfield Metro Center will include one million square feet of class A office space, a 180-key Hilton Hotel, 190 residential units and 30,000 square feet of retail space.

Cushman & Wakefield is in charge of leasing both the office and retail components at the site. Bruce E. Mosler, chairman of global brokerage; EVP Joseph A. Cabrera; and senior directors Stephen F. Baker and Michael B. Gordon are heading up the office component. Director Skip Lane and associate director Jessica Curtis are in charge of the retail space.

The Blackrock Realty entity developing the project is comprised of Fairfield-based Wittek Development and New Rochelle’s Rugby Realty.

Blackrock Realty principal Kurt Wittek said at Friday’s ribbon cutting that the firm was “delighted that the Fairfield Metro train station has been completed.” He added that a great deal of progress at the site had been made, citing the placement of footings and foundations for the Concourse Building and a fully developed waterfront park and nature preserve.
