DEVELOPMENT OF FREEWAY SYSTEM BY STAGES

THE STAGE DEVELOPMENT OF A FREEWAY SYSTEM INCLUDES: (1) THE FACTORS THAT DICTATE THE NECESSITY FOR STAGE CONSTRUCTION, (2) THE TIMING FOR THE VARIOUS STAGES OF DEVELOPMENT, AND (3) THE STRATEGY OF FREEWAY DEVELOPMENT TO DISCOURAGE USE OF EXISTING CONVENTIONAL HIGHWAYS IN THE FREEWAY CORRIDOR. FACTORS CONSIDERED NECESSARY FOR PROGRAMING THE INITIAL STAGE OF A FREEWAY ARE: (1) THE ULTIMATE RIGHT OF WAY REQUIREMENTS FOR THE PROPOSED FREEWAY MUST BE ACQUIRED, INCLUDING ACCESS RIGHTS WITHIN THE APPROACH AREA OF A FUTURE SEPARATED CROSSROAD WHICH WILL BE EITHER ELEVATED FOR AN OVERPASS OR DEPRESSED FOR AN UNDERPASS OF THE FREEWAY AS WELL AS ACCESS RIGHTS FOR THE FREEWAY LANES AND PROPOSED FUTURE INTERCHANGES, (2) CLOSE ALL CROSSROADS PROPOSED TO BE CLOSED IN THE ULTIMATE STAGE, (3) CONSTRUCT ALL FRONTAGE ROADS REQUIRED DUE TO ROAD CLOSURES, (4) CONSTRUCT THE NUMBER OF LANES NECESSARY TO ACCOMMODATE NO LESS THAN TEN YEAR TRAFFIC REQUIREMENTS, (5) GRADE SEPARATIONS AND INTERCHANGES REQUIRED FOR SAFE TRAFFIC OPERATIONS OF VOLUMES PREDICTED FOR AT LEAST A TEN YEAR PERIOD SINCE SIGNAL LIGHT OPERATION ON THAT SEGMENT WOULD NOT BE EXPECTED WITHIN THAT PERIOD, AND (6) CERTAIN ECONOMIC CONDITIONS WHICH MAY PROVIDE A FINANCIAL ADVANTAGE TO CONSTRUCT THE ULTIMATE DESIGN OF AN ITEM. AFTER COMPLETION OF THE FIRST STAGE, THE FACILITIES SHOULD BE UNDER CONSTANT SURVEILLANCE FOR OPERATIONAL AND SAFETY DEFICIENCIES TO BE CORRECTED TO COMPLY WITH FREEWAY DESIGN AS SOON AS POSSIBLE. CONSTRUCTION OF FREEWAYS IN MICHIGAN IS REPORTED. TRAFFIC OPERATIONS PERSONNEL IN MICH. ARE NOT ELATED OVER A DECISION TO STAGE CONSTRUCT A FREEWAY BECAUSE THE ACCIDENT POTENTIAL IS GREAT. THE FOUR-LANE DIVIDED EXPRESSWAY WITH ONLY PART OF THE CROSSROADS SEPARATED AND ONLY PART OF THE INTERCHANGES CONSTRUCTED HAS PRODUCED ACCIDENTS AT THE REMAINING AT-GRADE CROSSINGS IN MANY AREAS GREATER THAN THE ACCIDENT RECORD OF THE OLD TWO-LANE FREE ACCESS HIGHWAY. SOME OF THE PROBLEMS ENCOUNTERED IN COMPLETING THE FINAL STAGE OF A FREEWAY SEGMENT ARE DISCUSSED. ALTHOUGH PERMITTED BY MICHIGAN STATE LAW TO ACQUIRE RIGHT OF WAY IN ADVANCE OF CONSTRUCTION, MICHIGAN DOES NOT HAVE A REVOLVING ADVANCED RIGHT OF WAY ACQUISITION FUND. THIS POLICY GIVES A SERIOUS FINANCIAL PROBLEM AFTER STAGING CONSTRUCTION OF A FREEWAY IN AN URBAN AREA. TRAFFIC OPERATIONAL PROBLEMS ARE CITED AND DISCUSSED. IT IS CONCLUDED THAT STAGE DEVELOPMENT DOES GIVE THE OPPORTUNITY TO EXPAND SYSTEMS, SERVE A GROWING ECONOMY AND STILL HAVE A PERSPECTIVE FOR REVISION OF CONCEPTS AND IMPROVEMENT IN FACILITY DESIGN.
