MathBabbler found a collection of I-10 road signs at Interstate-Guide.com while working on a BAB about the number 10.

Interstate-Guide.com::The numbers are: 10, 1, 14, 9

+---------------------------+ +-------------+ | I-10 Santa Monica Fwy & | | 14 ft 9 in | | Coast Rte CA-1 | +-------------+ +---------------------------+the math is: 10 + 1 + sqrt(9) = 14

Interstate-Guide.com::The numbers are: 10, 1, 14, 7, 35

+-------------+ +-----------+ | I-10 Fwy | | CA-1 | | Los Angeles | | Coast Rte | +-------------+ +-----------+ +-------------+ +-------------------------+ | 14 ft 7 in | | Warning - Curve 35 mph | +-------------+ +-------------------------+the math is: 35 / 7 + 10 - 1 = 14 more math: sqrt(sqrt(35 - 10) - 1)) * 7 = 14

Interstate-Guide.com::The numbers are: 1, 3/4, 4, 5, 1, 3 1/2

+-----------------------------------+ | Lincoln Blvd / CA-1 South 3/4 | | 4th & 5th St 1 | | Chautauque Blvd 3 1/2 | +-----------------------------------+rsPhiEval: (1 + sqrt(5)) / ((4 - 3 1/2) / (1 - (3/4))) = Phi more math: avg(5, (1 + 1) * (3 1/2)) = ((3/4) * 4)!

Interstate-Guide.com::The numbers are: 1, 4, 5, 1/4, 1

+--------------------------+ +-----------------------+ | North Pacific Coast Hwy | | 4th St CA-1 South | | CA-1 Oxnard | | 5th st Lincoln | +--------------------------+ | 1/4 Mile Blvd | +-----------------------+the math is: 1 / (1/4) + sqrt(4) - 1 = 5

There were more road signs (I-10 is ~2460 miles long), but MathBabbler has saved them for another day.
