road was about $89 million. Most tolls were doubled on January 1, 1987. Eastern extension Prior to the start of construction on the eastern extension, the Northeastern Beltway (State Road 417) was built north from the existing east end of the East–West Expressway at Colonial Drive. As part of this project, in 1987 and 1988, two ramps were added to the Goldenrod Road interchange to make it full, and the three at-grade intersections were removed – Chickasaw Trail became an overpass, Valencia College Lane became an interchange, and Millinockett Lane was simply cut. Ramp tolls were added at Valencia College Lane and SR 50, adding to the cost of traveling the original East–West once tolling on the new road began January 1, 1989. By 1984, the alignment of the eastern extension of SR 408 had been chosen. The area was planned to be developed, and the OOCEA hoped to build the road before development made that impossible. Construction began in 1987, and the west piece, from existing SR 408 (redesignated SR 4080) to Rouse Road, opened May 12, 1989. The rest of the six-mile (10 km) road opened in June, with a total cost of $105 million. This project included a full interchange with the planned Southeastern Beltway (opened April 14, 1990), the Dean Road barrier toll, as well as a connection at the east end to the Central Florida Research Park. A wide median was left where the road curves north to end at SR 50 for further extension, but the land to the east has since been developed. Western extension A connection to Florida's Turnpike and the planned Western Beltway was studied in 1985. (The Beltway, which would have run where Clarke Road now is, was soon shifted west.) Construction on the 4.5-mile (7 km) extension began in mid-1989 and was completed on October 8, 1990, costing $102 million total. The former west end at SR 50 west of Kirkman Road was temporarily designated SR 4081 during construction, and became a retention pond. A fourth barrier toll – the Hiawassee Road plaza – was added to the road. The extension was designed to have a full interchange with the Turnpike, but originally only the north-pointing ramps were built. The full interchange with the Turnpike was completed in August 2006. A temporary ticket system booth was installed until the Turnpike switched to a coin system in 1991. Later changes
