5 Calculation of detour length Distance along SR 10030.54 + 0.66 = 1.20 0.54 0.66 Distance along SR 23210.91 + 0.47 + 0.66 = 2.04 Total Miles= 3.24 0.91 0.47 0.66

6 Calculation of detour length Distance along SR 10030.54 + 0.66 = 1.20 1.47 Distance along SR 23210.91 + 0.47 + 0.66 = 2.04 Total Miles= 3.24 0.66 Length of road normally travelled Distance along SR 23201.47 + 0.66 = 2.13 Additional travel length due to detour Detour length – length normally travelled 3.24 – 2.13 = 1.11

7 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 times 60 / Speed limit (1.11 miles)(60)/45 = 1.48 minutes Designated detour is acceptable according to the guidelines

8 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 times 60 / Speed limit (15 miles)(60)/45 = 20 minutes Designated detour is unacceptable according to the guidelines
