Someone approaching the plant from the north will see a sign placed by Erie County crews at the intersection of Aqua Lane and Sheridan Drive, just outside Aqua Lane Park, warning the trail is closed off 2,300 feet ahead.

Corrigan, in his letter, said he didn't see anyone doing work there when he visited on a recent weekday and he worried the company had "no great urgency to finish it."

On Saturday, Mike Holler and his son Zander, 13, were sitting on a park bench just to the north of the work site enjoying the sunshine and the million-dollar riverfront view. The Hollers had ridden their bikes about 6 miles from their City of Tonawanda home and they typically stop there to rest before the return trip because they know they can't go any farther.

"We used to go all the way down to the Peace Bridge," said the elder Holler, who looks forward to seeing the repairs completed.

Messore said the work was originally expected to be finished by the end of August, but now the lead contractor, State Group, informs her it should be completed by the end of this month.

That's also what GM and the contractor have told county parks officials. Deputy Parks Commissioner Greg Olma said the county gets regular calls from trail users asking when the path will reopen.
