Miami Wants Skinnier Lanes On Highways

In Miami, many plans are brewing for major highway facelifts -- including the creation of a four-level highway interchange. In the meantime, the region looks to deal with congestion by thinning highway lane widths to create more room for traffic.

"The state Department of Transportation said last month it is considering narrowing lane widths on Interstate 95 to eke out a couple of extra travel lanes in Miami-Dade as part of a broader plan to create variably priced toll lanes from Interstate 595 in Broward to downtown Miami."

"Now the Miami-Dade Expressway Authority is getting into the act, trying to squeeze additional capacity onto the Dolphin Expressway (State Road 836) without spending tons of money to buy or take additional land near the overburdened toll road."

"The lane would be used to help traffic flowing eastbound in the mornings and westbound in the evenings. Access and exit would be controlled by concrete barriers that would be opened and closed -- 'zipped' and 'unzipped' -- depending on the time of day."
