Interstate 74 Quad Cities Corridor Study, Scott County, Iowa and Rock Island County, Illinois


Book Description

The Iowa and Illinois Departments of Transportation (DOT) and the Federal Highway Administration (FHWA) are proposing improvements to the Interstate 74 (I-74) corridor in the Quad Cities from Avenue of the Cities (23rd Avenue) in Moline, Illinois, to 1 mile north of 53rd Street in Davenport, Iowa. The U.S. Coast Guard is a cooperating agency. The study corridor traverses the cities of Moline, Bettendorf, and Davenport and includes a crossing of the Mississippi River. Though I-74 is predominantly an east-west interstate, it is on a north-south alignment through the study corridor. As such, in this document direction of travel along I-74 is described as northbound or southbound to distinguish it from east-west traffic movement along cross roads. The I-74 study corridor is characterized by a mix of residential, commercial, and industrial development. Residential land use is present throughout the project corridor, but there are concentrations south of the commercial area in Moline and north of the commercial area in Bettendorf. Industrial land uses are mainly located along the river in Moline and Bettendorf. Parkland and open space can be found along the river in Moline and Bettendorf, and along Duck Creek in Bettendorf and Davenport. I-74 is the primary north-south roadway through the study area. As such, it carries a large amount of commuter and commercial traffic. The proposed improvements to I-74 include: Providing additional capacity on I-74; Improving the Mississippi River crossing; Improving the six existing service interchanges; Enhancing the connecting arterial roadway system; Improving opportunities for transit, bike and pedestrian, and intermodal connections.

Consideration of Environmental Factors in Transportation Systems Planning


Book Description

This report describes the transportation planning process and discusses where and how environmental factors can be addressed effectively at the state and metropolitan levels. This report should be especially useful to federal, state department of transportation (DOT), metropolitan planning organization (MPO), and local transportation planners, as well as other practitioners concerned with addressing environmental factors within transportation systems planning, priority programming, and project development planning leading to implementation. The research focused on environmental issues within the long-range transportation planning processes of state DOTs and MPOs and included the following: (1) a comprehensive review of recent literature; (2) a survey of approaches employed by state DOTs, MPOs, and environmental regulatory agencies; (3) a review of federal regulations and guidance on environmental factors; and (4) case studies to synthesize current practice in environmental planning.
