Over the years, it&#8217;s been improved in fits and phases across eastern and central Iowa, while the western part has fallen by the wayside.<\/p>\n<p>In the next five years, there will be a complete four-lane US 30 from Ogden to Lisbon. That leaves a 44-mile (or so)\u00a0two-lane portion between the end of the future Mount Vernon-Lisbon bypass and US 61. The Iowa Transportation Commission has &#8220;U.S. 30 corridor prioritization&#8221; <a href=\"http:\/\/www.news.iowadot.gov\/newsandinfo\/2017\/08\/iowa-transportation-commission-to-meet-in-shenandoah-aug-8.html\">on its meeting agenda for this month<\/a>, which I think relates to this.<\/p>\n<p>But \u2014 and I fully understand I may be about to commit heresy here \u2014 is four-laning 30 between Lisbon and US 61 the thing to do? Here&#8217;s my thinking behind this.<\/p>\n<ul>\n<li><em>Traffic count drops substantially in this corridor<\/em> compared with what&#8217;s west and east. <a href=\"https:\/\/iowadot.gov\/maps\/msp\/pdf\/VehicularTrafficMap.pdf\">See the 2014 AADT map.<\/a>\u00a0Between Stanwood and Grand Mound it&#8217;s comparable to US 63 in Tama County, <a href=\"https:\/\/iowadot.gov\/maps\/msp\/pdf\/TruckTrafficMap.pdf\">although truck traffic is higher<\/a>.<\/li>\n<li><em>The four-lane will have to be built from scratch.<\/em> Current 30 goes through seven towns on this stretch. The railroad parallels the highway throughout. To avoid the towns (and to avoid Yankee Run, a stream that parallels 30 on the south between Clarence and the Wapsipinicon River), a new roadbed would have to extended due west from a totally rebuilt south 30\/61 interchange, not angle north until Wheatland, and then stay at least a mile away from the current road. Unlike new US 20 in western Iowa, the new alignment will not be a straight line and there will be many more houses and natural features to deal with. And the EISs. OMG, the EISs.<\/li>\n<li><em>This part of the corridor may not serve as a popular alternative to I-80.<\/em>\u00a0IMO, it&#8217;s highly unlikely this would be built as a controlled-access freeway. Going through Clinton, a two-lane in Illinois, and a toll I-88 all work against US 30 being a long-distance alternative to the east. While US 30\/61 could serve as a relief route for I-380\/80 between Cedar Rapids and Davenport, how much would cross traffic and a 65-mph speed limit cut that attractiveness?<\/li>\n<li>The bright(ish) side for historic preservationists would be that the necessity of a new four-lane corridor could leave the Lincoln Highway and the new &#8220;old 30&#8221; intact \u2014 except maybe between Lisbon and Stanwood. That&#8217;s also the segment I could see being four-laned apart from the rest with the most need (traffic-wise) and least difficulty.<\/li>\n<\/ul>\n<p>Instead of plowing ahead (if decades-in-the-making can be called such) with finishing the US 30 corridor here, I think serious consideration should be given to speeding up a timetable for six-laning I-80 between Davenport and Iowa City, and I-380 south of Cedar Rapids. That needs to be done <em>anyway<\/em>. Increasing capacity in those corridors could alleviate some of the traffic on 30 today.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Ever since the mid-1960s, US 30 has been viewed as an eventual four-lane corridor across the state of Iowa.
