Calculation of detour length
Distance along SR 1003 0.54 + 0.66 = 1.20
1.47
Distance along SR 2321 0.91 + 0.47 + 0.66 = 2.04
Total Miles = 3.24
0.66
Length of road normally travelled Distance along SR 2320 1.47 + 0.66 = 2.13
Additional travel length due to detour Detour length – length normally travelled 3.24 – 2.13 = 1.11
Additional travel length due to detour Detour length – length normally travelled 3.24 – 2.13 = 1.11
Estimated length of construction Simple 3 span bridge replacement project 10 months
Additional travel time due to detour Additional travel length times60 / Speed limit
(1.11 miles)(60)/45 = 1.48 minutes
Designated detour is acceptable according to the guidelines
Additional travel length due to detour Detour length – length normally travelled 15
Estimated length of construction Simple 3 span bridge replacement project 10 months
Additional travel time due to detour Additional travel length times60 / Speed limit
(15 miles)(60)/45 = 20 minutes
Designated detour is unacceptable according to the guidelines
