PARIS — Construction of a wall to keep migrants from reaching a road that leads to the French port of Calais will begin this month, officials said this week. The wall, a joint project by Britain and France, is the latest attempt to address security concerns and local displeasure with a ramshackle camp for migrants at the English Channel port.

“We are going to start building this big new wall very soon,” Robert Goodwill, the British immigration minister, told Parliament’s Home Affairs Committee in London on Tuesday. “We’ve done the fence, now we are doing the wall.”

The proposed wall will be four meters high, or about 13 feet, and will run for one kilometer, or about 0.6 miles, along both sides of the road that approaches the port of Calais, as an extension of the existing fence and barbed-wire barrier, according to the committee’s press office.
