Brown Deer Parkway Bridge


The East Face

As seen from across the east side of the lagoon. Many Milwaukee County Parks have bridges and structures build in this same depression-era style, using similar designs and lannon stone as the primary material.

Lannon Stone 

Written by J.R. Manning

"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, right here 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.
