The Riverside Galleria is slated to be built on 18 acres of waterfront property off Arthur Kill Road near the Outerbridge Crossing.

It’s supposed to offer shops, restaurants and the borough's first dine-in movie theater, but the project's future now looks bleak.

"This is sort of good night on this project,” said Borough President James Oddo on Tuesday.

Oddo initially supported the idea of building the upscale, outdoor shopping mall in the Charleston section of Staten Island.

That was until the release of a study which showed the area won't be able to support an influx of cars.

"There’s no getting around the fact that this will be a traffic nightmare,” he said.

According to the report compiled by several city agencies, the project would cause "unavoidable significant adverse transportation impacts related to traffic."

The Department of Transportation analyzed 20 intersections near the proposed site and projections showed major delays in 15 intersections during peak travel times.

The analysis also identified six intersections that could not be mitigated whatsoever.

Although developers reported the project would have introduced nearly 1,300 job and almost 4 acres of open space, Oddo said the benefits don't outweigh the challenges in infrastructure.

"That queue [to get into the mall] would have gone all the way back, and that would have been life in that area weekend and week out," he said.

The project's developer remained optimistic in a statement released to NY1.

“Clearly we are disappointed with the Borough President and Councilman's withdrawal of their support of our project. Our interest has always been to develop a world class retail center which would enhance the community and work towards economic development for the South Shore and all of Staten Island. We respect the Borough President and Councilman's concerns and take them seriously. It is our hope that we can work together towards a future plan they can support," wrote Robert Konig, Executive Project Manager, Riverside Galleria. 

However, Oddo said that is unlikely.

“I don’t see how you make the pieces of this puzzle fit. If they want to continue to try- that’s on them but I don’t see how you fix this traffic nightmare and I think sadly- the traffic volumes only get worse as time moves on. So I don’t see my opinion of this project changing in anyway shape or form it just doesn’t fit,” he said.

South Shore City Councilman Joe Borelli also withdrew his support- support considered crucial for the project to move forward.
