Nine alleys and lanes in Harrison are on deck to be improved this year.

The township is seeking bids for contractors to seal coat or tar-and-chip the roads. Bids, which are due by 4 p.m. March 15, will be publicly opened and read aloud at the office of the township’s engineer, NIRA Consulting Engineers, at 950 Fifth Ave. in Coraopolis.

Harrison has been using shredded fiberglass fibers to seal coat alleys in recent years to help seal cracks and extend the life of the pavement, said Raymond Antonelli Jr., vice president of NIRA Consulting Engineers.

The township is expecting the work to cost about $54,000, according to its bid advertisement.

The roads slated to be worked on are an unnamed alley between Springhill Road and Harvard Ave­nue; Westminster Alley west of Freeport Road; Montrose Alley between Fairmont Street and Dallas Avenue; Mayflower Alley between Dallas and Princeton avenues; Earnhardt Way between Poplar Street and Springhill Road; Elder Alley between Second and Third streets; School Alley between Third and Fourth streets; Orinoco Alley east of Freeport Road; and Logan Lane west of Freeport Road.

Copies of the bid documents can be examined at the township secretary’s office at the municipal building or at NIRA Consulting Engineers.

When the work will be done is not known. Antonelli said they will want the contractor hired to wait until warm weather arrives.

“This type of application is best performed in hot weather when the pavement is hot,” he said. “We like to bid early to try to get the best prices.”

Harrison also will soon be seeking bids for asphalt paving to be done this year, Antonelli said.

The documents for that work are not yet completed, he said.
