Traffic Engineering does not recommend Option #2, because of the possible safety problems associated with the arbitrary placement of "STOP" signs and speed bumps. u r.ion .s: cnan a 16th Street to "RIGHT TURN ONLY" AT 58th Avenue Changing westbound 16th Street to "RIGHT TURN ONLY" at 58th Avenue would not result in a drop in level of service at the intersection. Motorists desiring to go south on 58th Avenue (approximately 25 per peak hour) however would be required to turn right and then u -turn across 58th Avenue. Traffic Engineering does not recommend Option #3, because of the increased delay to southbound motorists. Traffic Engineering recommends shortening the proposed left turn lane to minimize storage. We are working with Rimley-Horn to make the required changes. Director Davis advised that staff plans to begin the bidding process within a year to widen 43rd Avenue. One left turn lane onto 16th Street=i-s contemplated in that widening process. Director Davis stressed that eliminating the bridge at 16th Street/58th Avenue would degrade the level of service of 43rd Avenue and SR -60 and divert more traffic south to 12th Street. Staff feels an important objective is to maintain the consistency of the 1/2 mile spacing roadways. With respect to additional stop signs, he explained that there is specific criteria for the installation of stop signs in the Manual of Uniform Traffic Control Devices adopted by Florida Statutes. As to the bridge design, he advised that staff expects to go to bid in late summer on the project and cited several reasons why it is inappropriate to redesign it. Director Davis explained the drawings that appear below. He described how -staff --:had worked with and tried to adjust plans to suit Dr. and Mrs. Vinson. _The Vinson are not willing to sell any of their property for right-of-way to accommodate a transition lane so staff has had to reduce the right-of-way needs and the storage of the left -turn lane. 21 April 8, 1997 BOOK .10i PAGE
