Summary Information

A dynamic curve speed warning sign using radar detection is estimated to cost between $9,000 and $14,000, with the price dependent on the type of warning systems used. The sign would be solar powered and the cost of replacing the battery would be $160 for each replacement. Battery lifecycle is 4 to 7 years, lasting longer in colder conditions. Barring lightning strikes or damage to the sign as the result of a crash, the lifecycle for the sign is 20 years.

Minnesota DOT estimates that it would cost approximately $2.5 million dollars over 20 years to place signs on 204 curves and replace the batteries every four years.
