1934 WEST NORTH AVENUE BRIDGE U.S. PUBLIC WORKS PROJ. N.R.S. 524 - A BUILT BY WISCONSIN HIGHWAY COMMISSION IN COOPERATION WITH THE U.S. BUREAU OF PUBLIC ROADS CONTRACTOR JACOBUS & WINGING CONCRETE CONSTRUCTION CO. WAUWATOSA, WISCONSIN
"Lannon Stone" is a building material that is commonly used in the Milwaukee area. It was used extensively in Milwaukee County Parks during depression era construction projects for structures of all kinds, many of them were WPA projects.
From tiny control buildings to arch bridges to structures of many kinds, Lannon Stone is ubiquitous, even moreso than Cream City Brick, also a common building material in the area. Many county golf course buildings are constructed of the attractive, white stone, including clubhouses. For example, the impressive club house that overlooks the golf course in Brown Deer Park, is constructed of Lannon Stone. Brown Deer Park is the location of a PGA golf tournament, formerly known as the Greater Milwaukee Open.
The stone is actually dolomite but takes its name from the area, northwest of Milwaukee, from which it is quarried.
This bridge uses "Lannon Stone" for facing and parapet walls.
