OCT 81980 44 PAGE,868 Location #3 - SR 60 & 43rd Avenue This intersection is approximately seven to 8 years old and has apparently never had a conflict monitor. It is an electronic controller and the absence of the conflict monitor could create a potentially danger- ous and liable situation in the event of an untoward controller failure. This is required under Florida State requirements to meet current specifications. Cost approximately $800 Location #7 - US -1 & SR5-A This intersection is 10 to 12 years old and the control equipment is completely obsolete Considerable difficulties are experienced and a high degree of unreliability for mechanical type relays has been the cause of a number of failures. There is no conflict monitor installed on this controller. Also, the span wire system should be updated to a dual span wire proper height and 12" dual --signals in- stalled. The intersection has been struck a number of times because it is low and cannot be raised without a com- plete rebuild. Estimated cost for re- placing the controller, upgrading the span, replacing the necessary sigtn:ils for dual indications, etc. - $10,000. Location #8 - U.S.-1 & 87th St. Traffic signals are low and cannot be raised due to configuration of the inter- section. This should b�-rebuilt to a double span wire system and replace signals to conform to current standards. Estimated cost - $5,000. Location #10 - U.S.-1 & 12th Street Controller is a completely obsolete electro- mechanical system for which parts are generally not available. Timer cabinet, etc should be replaced and intersection raised to proper height and brought up to current dual indication standards. Estimated cost $12,000. Location #20 - SR605 & 12th St. Loops are bad on the south approaches and need to be replaced. Estimated cost $300. Location #21 - 20th Ave. and 12th Street Indications should be updated to dual 12" signals and an additional 3 section 2 way signal assembly complete with all hardware etc. to bring up the indications in all four directions. Dual span should be in- stalled and complete overhead system rebuil, Estimated cost $3,500. These are the major capital improvement and replacement intersections. Other items are being picked up on a routine basis under your mainten- ance contract and if further discrepencies are discovered we will advise you. Yours truly, SIGNAL CONSTRUCTION COMPANY, INC.
