U.S. Homeland Security Secretary Jeh Johnson says federal officials are working on securing funds for a customs plaza to support the planned New International Trade Crossing between Detroit and Windsor, Ontario.

However during a press conference in Detroit, Johnson stopped short of saying when the project will see the $250 million in funding.

Johnson visited the current customs plaza of the Ambassador Bridge, as well as the proposed landing site for the U.S./Canadian venture.

Canada has already pledged $630 million dollars over a two-year period to build the bridge but President Barack Obama’s budget proposal released in March did not contain a U.S. contribution toward the project that is expected to cost $2.1 billion.

The bridge is widely supported by business and government interests in Southeast Michigan and across the border who claim it's essential for job growth and increasing trade however it has faced opposition by the owners of the Ambassador Bridge.

Johnson also traveled to Port Huron and toured operations at the Blue Water Bridge.
