Minnesota Standards Should Change from 12 Foot Lane Widths to 11 Foot Lane Widths - Mike on Traffic

Mike on Traffic argues:

Minnesota Standards Should Change from 12 Foot Lane Widths to 11 Foot Lane Widths : ""

"Narrowing roads results in shorter crossing distances and reduced traffic speeds. This improves the environment for pedestrians and bicyclists. The research also points to 11 foot lanes being as safe as 12 foot lanes (according to NCHRP Project 17-26). A big reason is that motorists drive more cautiously in narrower lanes. Narrower lanes would have reduced the numerous speeding complaints I received from residents during my tenure in Maple Grove. A quick check of MnDOT's website shows there are 290,588 lane miles in Minnesota. Assuming we trimmed one foot off each lane, that would equate to 35,222 acres (55 square miles) of less pavement (assuming all of the roads are paved). To put that in perspective, the city of Minneapolis is 58.4 square miles including the lakes and rivers. Imagine the economic and environmental benefits of shifting the standard by one foot. Why would this decision take 2+ years of study? The rules should be re-written to make 10 foot lanes allowable in urban settings, 11 foot lanes the standard across the state, and 12 foot lanes allowed if justified through a variance process."
