Madison Bike Lanes 1: The Intersection Valley Gutters

This is the first of many blogs that will highlight the multi-step process of installing bike lanes onto Madison.  The first step was to replace a few valley gutters at intersections along Madison.  Intersection valley gutters are concrete surfaces designed to enable water to cross an intersection rather than flow along the curbs.  One such valley gutter is on my block at North Auburndale.

To avoid the complete closure of an intersection, the valley gutter was installed in two phases.  The eastern half of this valley gutter was replaced first.

Once the concrete dries, it becomes as white as the new sidewalk ramp.  And yes, that is a kilt.  Remember, nothing ever happens on my block.

The western half came next.  Note the thickness of the subsurface of the street.

...taking a break.
