This is a complex project that requires a redesign of the roadway layout to fix the current sidewalk issues. This infographic/handout (PDF) shows the changes that the roadway design will undergo. There are four different breakouts because each segment requires a different type of fix.

Fourth Street North to Broadway Street (Hwy 175)
This layout only changes by switching the boulevard and the sidewalk along the northbound lane, there is no curb shift.
Broadway Street (Hwy 175) to 10th Street South
This layout changes by replacing 4 feet of the paved shoulder on the northbound lane with concrete sidewalk.
Emerson Avenue to Atlantic Avenue (Hwy 75)
This layout changes by replacing a total of 6 feet of the paved shoulders with a new boulevard space on the westbound lane.
Atlantic Avenue (Hwy 75) to Two Rivers Bridge
This layout changes by replacing a total of 4 feet of the paved shoulders with a new boulevard space on the eastbound lane.
Although there are a number of considerations when taking a curb shift into account, in this circumstance the amount of pavement space must be reduced and a curb shift must take place.
In order to accommodate the minimum requirements needed to reconstruct sidewalks that meet ADA standards, the sidewalk slope has to be extended into the current pavement layout. A curb shift is the only way to feasibly accommodate that.
