Lincoln's problems can be summed up pretty easily:
Heading North/South, there isn't a four-lane street that goes completely through town between 10th and 84th - a distance of five miles.
Heading East/West you have more four-lane options, but not many. O Street is four lanes throughout Lincoln. North of O, your next four-lane street through town is Superior, three miles north of O. Your first four-lane street going East/West south of O is Old Cheney (minus the part through Wilderness Park), which is four miles south of O st.
Granted, there are a couple of arterials that snake their way through parts of town like Cornhusker HWY north of O which goes SW to NE, and Capitol Parkway/Normal Blvd and Highway 2 which both run NW to SE south of O street, but if you're going across town these are often not good options.
Lincoln is a larger town with a small-town mentality, and there is a huge contingent of Lincolnites who want to keep it that way - and they vote and support candidates who feel the same. This has led to a failure to properly plan for growth going back decades, resulting in very haphazard growth that is often hindered by special interests (such as the Country Club, the single biggest impediment to widening 27th street to four lanes through town).
The most ignorant thing about Lincoln is that they have bound themselves up in impediments to growth, while at the same time existing in the midst of open farmland ripe for that growth. There are no natural barriers to proper growth for this town - no large rivers, lakes, mountains or seas. Instead, Lincoln does stupid things like planting Wyuka cemetery right on its major thoroughfare, and putting plots so close to the street that it's now impossible to widen the street any further (and it needs widening, right now). They have major thoroughfares which end abruptly in unmodifiable blocks, such as 40th street at O street, Vine at 84th and at the UNL campus, 48th at Old Cheney, Holdrege at the UNL Campus, 33rd at Antelope Park and at Cornhusker HWY, 56th at Fremont St, Van Dorn st at 56th, and South st at 70th. That's most every major arterial blocked by some immovable impediment.
Who does that? Who thinks that's appropriate city planning? A City Council who has no plan, that's who.
