The Third Cape Cod Canal road bridge is a proposed bridge that would cross the Cape Cod Canal in Bourne, Massachusetts. A third bridge has been planned on and off since the state of Massachusetts stated that the bridge would be necessary after 1975 for a third crossing, with another proposal in that era proposing it as part of the Southside Connector. although a 2013 report suggested building the bridge adjacent to the Sagamore Bridge in order to ease traffic on the structure. ==Background== A third bridge over the Cape Cod Canal was first proposed during the 1950s to connect the proposed Route 25 to U.S. Route 6 north of the canal. The state of Massachusetts determined that due to overcapacity on the Sagamore Bridge, a third vehicular crossing would be necessary sometime after 1975. Another proposal, for the Southside Connector expressway, proposed twinning the Bourne Bridge as part of capacity improvements for the roadway.〔 A local farmer fought the state's effort to cross her land with Route 25 for 25 years, eventually winning that fight in 1982. In recent times, the proposal has shifted to building a bridge alongside the existing Sagamore Bridge, or building one between the bridges. The proposal for the bridge next to the Sagamore Bridge would involve a bridge to the west of the current structure, which would contain three southbound lanes, which would then give added capacity to the Sagamore Bridge and allow for extra room on the narrow lanes. This proposal would allow for open-road tolling, so that drivers would not have to slow down. It would also involve an access road between Route 25 and Route 3, again proposed to cross the same farmland, which former Massachusetts Highway Administrator Frank DePaola admitted presents environmental challenges. The proposal for putting the bridge between the two bridges would involve a four-lane span, similar to the existing bridges. Both bridges are currently being proposed to exist as part of a public-private partnership, which is supported by Governor Charlie Baker. State Senator Dan Wolf has also suggested the state first consider allowing a public agency to do the job, in order to keep costs lower overall.〔 In October 2014, an event was set up for people interested in financing a separate high-speed toll lane along Route 3 and a new bridge. Over one hundred participants attended, which is considered to show a strong amount of interest in the idea. As of May 2015, the project is in the planning stages. 〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Third Cape Cod Canal road bridge」の詳細全文を読む スポンサード リンク
