in March 2011, and the portion between Beulah Road and SR 50 (exit 272) was completed in 2012. In 2007, legislation was passed in Florida to index toll rates across the state to the national Consumer price index (CPI), to be enacted by the end of June 2012. As a result, the toll rates on roads on Florida's Turnpike Enterprise were raised on June 24, 2012, an increase of 11.7% to reflect the previous five years. The legislation allows for SunPass rates to be raised slightly each year, with cash rates going up every five years, with SunPass rates staying about a quarter cheaper than cash rates. In keeping with the legislation, SunPass and toll-by-plate rates were raised again on July 1, 2013 by 2.1%, with cash toll rates projected to stay the same through at least 2014. Toll rate increases were scheduled for every five years, and mid-2017 was the next scheduled date for such an increase. However, a combination of a low inflation rate and problems within the relevant state authorities caused multiple cancellations and changes in schedule for the next increase. The final projected date for an increase in tolls was eventually set for October 29, 2017. The Turnpike Enterprise and OOCEA (now CFX) agreed to build a partial interchange between SR 417 and Florida's Turnpike in the late 2000s, after negotiations dating back to a 1991 field study. The interchange is being built in two phases. The first phase, built by CFX, added ramps from southbound SR 417 to southbound Florida's Turnpike and from northbound Florida's Turnpike to northbound SR 417. Construction on the first phase began in September 2013 and opened on January 26, 2015. The second phase, completing the interchange, was built by the Turnpike Enterprise. After a series of delays, construction began in 2017 and the completed interchange was fully opened on May 21, 2021. As part of the project, the turnpike mainline was widened from four to eight lanes between Osceola Parkway (exit 249) and the Beachline Expressway (SR 528, exit 255). Future Plans are in the works to widen the Turnpike from the Lake Worth Road interchange (exit 93) to the State Road 70 exit (exit 152) and from SR 50 (exit 272) to U.S. 27 (northbound exit 285) from four to eight lanes. In Miami-Dade County, several widening projects including new express lanes are underway. Reconstruction of the northern end
