The way Moore described it, "A car that comes up to the interchange, they usually have to stop at the first light. In this, all the ramps are curbed into the middle."
Moore said this is not the first time a traffic design like this was used to regulate the flow of traffic.
"This has been around since the 1970s in other states," said Moore. "Florida has some, Maryland has a lot. You also see them in California."
Hogan said the new interchange should improve traffic in the Town of Colonie significantly.
"I think it's going to get people through the intersection a lot quicker than they're getting through now. Just that alone will help the traffic flow," he said.
Hogan said this, along with construction on Wade Road should help make traffic in the town a lot safer.
Moore said that although it isn't the first SPUI in New York, the one at Exit 6 will be different from others in the state.
"New York state actually has the first one in the state where all the ramps come together over the roadway," said Moore.
In other SPUIs, Moore said, the ramps come together under the roadway.
In terms of construction, Moore said, the beginning stages, which include creating an auxiliary lane on I-87 that connects exits 5 and 6. During the entire project, Moore said he does not project lane closures during peak hours, and that they will mostly occur at night.
Construction of the SPUI will mostly occur in 2010, Moore said.
"We don't anticipate there to be significant impacts from construction until 2010," he said. The project is expected to be complete in October 2010.
While Moore said the department spent time developing a plan that would involve little impact to residents and businesses while construction is under way, the DOT has been trying to inform residents of alternate routes. These routes can be found on the project Web site at www.exit6.org
