Authorities are upgrading two vehicular routes into the Florida Keys through a series of projects set to continue to 2012, according to local and state transportation officials.
Work is in progress on a section of the Florida Keys Overseas Highway (U.S. 1) known locally as the 18-mile Stretch connecting the South Florida mainland with Key Largo. This road is shaded in red on the map at left.
Most of the work is occurring off the existing road to minimize inconveniences for motorists. Currently, construction is occurring between mile markers 106 and 116. Since speed limits are reduced in these areas to protect workers, motorists should allow at least a quarter-hour extra travel time.
Card Sound Road, also known as State Road 905, is an alternative route in and out of the Keys. That road, from Miami-Dade County to Monroe (the Keys) County has been repaved, but additional work is underway involving bridge maintenance and other enhancements. Travelers on certain sections of Card Sound Road may encounter delays due to alternating north and southbound traffic flow.
There is a $1.00 toll for each two-axle vehicle and 50¢ for each additional axle to traverse Card Sound Road. There are no toll charges on U.S. 1.
