ASHWAUBENON – The National Railroad Museum’s request for approval of a site plan for a proposed 32,040-square-foot addition to its Lenfest Center was approved unanimously at the Jan. 3 meeting of the Ashwaubenon Site Plan Review Committee.

The addition will primarily extend towards the Fox River, on the eastern end of the existing Lenfesty Center, but will also add space north of the existing building.

A covered patio will extend from the proposed addition and a concrete sidewalk is planned to extend around the outside of the addition parallel to the rail line.
