NASHUA — So far, about 17,000 cubic yards of asbestos has been mitigated and disposed of during construction on the Broad Street Parkway.
That amount, according to project manager John Vancor, is slightly less than expected. Initially, crews were anticipating that 16,500 cubic yards of asbestos would be encountered and disposed of on site, in addition to 3,000 cubic yards that would have to be taken off of the site for disposal, he said.
"All of the asbestos encountered has been disposed of," said Vancor, adding two independent teams of professionals are making sure that all asbestos safeguards are in place.
The majority of asbestos has been located within the northern portion of the roadway work, although a small amount has been found elsewhere, according to Vancor.
Aside from the asbestos, crews are now dealing with problems of urban fill found inside certain areas of the project that must also be disposed of, he explained.
Progress on the Broad Street Parkway, a nearly two-mile urban roadway that will provide another crossing over the Nashua River, is moving ahead on schedule and on budget.
"There is quite a bit of activity going on," Vancor said this week.
He said a retaining wall is being constructed, a new sewer pipe has been installed and a trestle into the river is underway.Earth work has also begun in the north sector of the roadway project, according to Vancor, who has heard complaints about vibrations at nearby buildings."I know there is a lot of concern," he said, acknowledging there is quite a bit of ground vibrations. However, he stressed that no blasting is taking place as part of the Broad Street Parkway project.
As construction progresses, he said there are still properties that must be acquired to pave way for the roadway. Acquisition of those properties by the state Department of Transportation is ongoing, said Vancor.There are some surplus properties no longer needed for the parkway since its original route was altered. Vancor said those properties must be sold within the next year to help offset the bond, otherwise the money will be returned to the federal government.One of the surplus properties includes the Nashua Police Department's current training facility.
Alderman-at-Large James Donchess said he would like the city to retain that parcel at 82 Pine St. Ext., questioning Vancor this week on whether keeping that property would be feasible. Donchess also asked whether some of the surplus properties could be leased by the city.
Vancor said he would have to seek clarification on those matters.
In the meantime, he said there is still some demolition that remains at 44 Broad St., a parcel that was previously taken by eminent domain as part of the Broad Street Parkway project but is no longer necessary for the revised path of the roadway.
The parcel, which is now being used as a staging area for one of the parkway contractors, was previously occupied by Mayhem Ink, Aidan James Salon, Wizard Cycles and Gregory J. Fine Flooring and Design. The plot was originally considered for the relocation of the David W. Deane Skateboard Park, but other sites are now being evaluated for the park.The Broad Street Parkway, which will cost about $60 million to complete, will provide another crossing over the Nashua River and allow motorists to bypass Amherst Street, possibly alleviating downtown traffic and potentially attracting more business to the Millyard Technology Park.
Construction includes a new Nashua River Bridge, as well as construction to the Baldwin and Fairmount Street bridges. Work has already begun on Baldwin Street, and the bridge there is expected to be completed by the start of the next school year.
Work on the Fairmount Street Bridge will begin once Baldwin Street is finished, and that section of the project should be completed in about a year. The new Nashua River Bridge will be finished prior to that, with an opening date planned for May 1, 2015.
