WESTBROOK – Replacement of an existing gas line will require some night work along Main and Cumberland streets during the next few weeks.

The Westbrook City Council unanimously voted Monday to approve a request from Unitil, the company that supplies natural gas to the area, to conduct night work along Main Street from Harnois Avenue to Cumberland Street, and along Cumberland Street from Main Street to Harnois Avenue.

City Administrator Jerre Bryant said the night work was necessary to minimize the disruption to traffic along the heavily traveled roads, adding that it would also be impossible to maintain two-way traffic while the work is being done.

In other news, councilors voted unanimously to approve the purchase of two police cruisers for slightly more than $51,000.

Bryant said the city would be purchasing two 2011 Ford Crown Victoria Police Interceptor model cars from MHQ Municipal Vehicles in Marlborough, Mass., the company that came in with the lowest bid.

Bryant said that the price of the two cars is a favorable one for the city, especially given the fact that Ford discontinued the Crown Victoria line in 2011. He added that the cars being purchased by the city are new vehicles, as a number of dealerships, in anticipation of the discontinuation, stocked up on 2011 models to be sold as new cars in 2012.

Because the two cars being replaced are also Crown Victorias, the city will be able to use equipment from the existing vehicles in the new ones, saving about $10,000 to $12,000.

Bryant said the vehicles would be delivered later this month and would be on the road soon after that.
