[QUOTE="CHenry, post: 2588649, member: 6281"] I agree it's not a perfect alignment. Its what we had to deal with. I looked at 4 alternates and in terms of cost, functionality, safety and impact to land owners (this was a biggy) we chose so simply improve the 2 curves within the existing tangent sections. We didn't want to cut more directly from town northwesterly across that wheat field and impact that farmers land more. We are not in the business of buying land if we can afford it. This alignment cost less, was perfectly functional and meets 70 mph design speed in terms of safety. The heavy presence of Braums trucks was also a factor to consider. The SL connections I agree are a cluster but I wasn't involved at that stage of design. Maybe I could have come up with something better, maybe not. I do the initial scoping/alignment selection with comparative estimates and then a panel of division heads decide on the final outcome. Sometimes a public meeting takes place to get landowner input but I'm not abreast of that process. The fill on that section was all for drainage purposes as well as high water history. In order to not have water standing in the ditch all the time, a minimum grade has to be laid. .003 is the least amount of grade we can use to drain a ditch. This means there has to be elevation change between point A and B. In this case a grade raise was all we could do and keep the finish grade above high water points. I dont get involved with pavement design so I cant speak on asphalt quality or other factors in the surface. It should be noted that several of our finished roads have won nationally in terms of finished product. They judge based on several items. Some roads the contractor screws up and theres not much we can do without bankrupting someone to tear it out and fix it, so it stays. The turnpike north of Yukon has 2 bridges that come to mind. That was a consultant engineers fault, they designed the pre-stressed beams with too much camber for the dead load. Its like a roller coaster and a huge embarrassment. [/QUOTE]
