Q8: For the bypass road, is there another landowner aside from the BLM to coordinate with?

A8: The bypass road for culvert 2 is on BLM land and needs to be constructed prior to the removal of culvert 2. The bypass road at culvert 3 on sheets 11 and 15 is existing and runs through a Linn County Campground. Limited time is available to close the campground and use as a bypass road. Contractor shall coordinate with the COR when the construction can take place and the COR will request the park closure with Linn County. Closure will occur in the second summer of the contract but needs to be arranged immediately to avoid conflicts with camp reservations.

Q9: Culvert 3, is there an agreement to use Linn County Campground traffic lanes as a bypass road? Including installing speed bumps?

A9: Upon discussion with Linn County, currently they do not wish to have the campground open during construction. Due to this, speed bumps and signs within the campground would be minimal. Linn County wants to limit the campground closure as much as possible. See answer to question 8.

Q10: Is the bypass road for culvert 2 different than culvert 3?

A10: Yes, the bypass road for culvert 2 will need to be constructed and is part of the work that is required to be completed with culvert 2. The bypass road for culvert 3 is existing and runs through a Linn County Campground.

Q11: Can we close Quartzville Rd at Culvert 3 while construction is taking place for the culvert?

A11: Per the temporary traffic control plan on sheet 15, Quartzville Rd is to be closed during the construction of culvert 3 with traffic being diverted onto the bypass road. Please see previous answers to this question.

Q12: For the speed bumps, are speed bump ahead signs required?

A12: Appropriate traffic control signage is required per the MUTCD. Please refer to sheet 15 of the project plans for specific traffic control through this area.

Q13: At MP 14.3 heave in road, does the contractor have to maintain two-way traffic or are flaggers required?

A13: The contractor is required to maintain 2-way traffic, one travel lane must always remain open with appropriate traffic control in place to accommodate 2-way traffic. Traffic may be placed on finish rock grade, however a ramp between the existing asphalt and the rocked lane must be kept and maintained by the contractor. Any damage to asphalt outside the excavation limits is to be removed and replaced at the Contractors expense.
