1. Two roadway designs are under consideration for access to a permanent suspension bridge. Design 1A will cost $3 million to build and $100,000 per year to maintain. Design 1B will cost $3.5 million to build and $40,000 per year to maintain. Both designs are assumed permanent. Determine which design is preferred at a MARR of 10% per year using the ROR analysis. (Hint: It will be easier to use an AW-based ROR analysis)
