opposed the proposal in early November 1974 as it would require approval from over thirty government agencies and would force the city to continue with building this road, although some declared it "impossible to build." The voters rejected this plan. The portion of SR 75 from Pomona Avenue in Coronado to Imperial Beach was also recommended to become a scenic highway in February 1974. Future improvements to the Imperial Beach – Coronado portion were cancelled in April. In 1976, the California State Legislature renumbered the portion from I-5 to SR 125 as SR 117, which later became SR 905. The change took effect at the beginning of 1977. The renumbering was to reduce confusion with the Coronado portion, according to Caltrans regional director Jacob Dekema; new signs were to be put into place shortly thereafter. The bridge and the resulting traffic continued to be a hotly debated issue in the early 1980s. A plan in 1981 to convert Fourth Street into an expressway leading to the naval station was strongly opposed by the public due to the required demolition of structures and a lack of evidence that the plan would succeed in reducing traffic; by this time, Third and Fourth streets had been converted into one-way streets between the bridge and the naval station. A major renovation of the bridge was scheduled for late 1992, which would include a movable barrier to prevent head-on collisions and necessary resurfacing of the roadway. Work was underway in January 1993 on the $4 million project (about $ in dollars), but it was behind the three-month schedule by 11 days due to rainfall and was expected to be completed by March. When the Coronado Bridge opened, a toll of 60 cents was charged to use the bridge. In 1980, the toll became $1.20, charged only in the westbound direction towards Coronado. A seventh toll booth was to be constructed in September 1987. The toll dropped to $1 in 1988. The bridge tolls ended at 10 p.m. on June 27, 2002, after the San Diego Association of Governments decided to stop collecting tolls; drivers paid a total of $197 million throughout the years. The speed limit was decreased to in October 2005 along Third and Fourth streets, after traffic increased by 20 percent following the removal of the toll. Traffic barriers along Third Street to block traffic from turning onto intersecting streets were removed in
