The price of the new football stadium for the New York Giants and New York Jets has risen to US$1.4 billion (euro1.1 billion).
"Costs continue to go up," said Alice McGillion, a spokeswoman for New Meadowlands Stadium Corp., a company that represents the team owners.
The teams, which are jointly financing the stadium, have made a significant step by awarding a mammoth contract to a Swedish construction company.
Skanska AB said Friday it had received a US$998 million (euro769 million) order to design and build the open-air stadium at the Meadowlands sports complex in East Rutherford, New Jersey.
"It shows the continued momentum and we are on the timeline that we need to be for a 2010 opening," McGillion said.
The stadium will seat 82,000 spectators and include 217 luxury suite boxes, Skanska spokesman Peter Gimbe said.
McGillion said the number of seats could change, depending on the final design.
Skanska said that the contract, with the Meadowlands NFL Football Stadium LLC, was its largest U.S. contract yet. The Swedish company will include it in its order bookings in the first quarter.
McGillion said the teams expect to unveil exterior plans for the stadium in late February or early March, with a ground breaking in late spring or early summer.
In December, the teams got a big boost from owners of the National Football League, who approved a US$300 million (euro231 million) loan to help fund the stadium.
The project is also going through the approval process with the state of New Jersey.
The state Department of Environmental Protection and the Meadowlands Commission expect a final environmental impact study of the project in February; their approval could come in March.
