m <br />DEPARTMENT OF <br />TRANSPORTATION <br />NORTHWEST METRO <br />Mississippi River Crossings Traffic Analysis <br />Overview and Need <br />Context and Land Use Traffic Analysis <br />Improvement Concepts <br />Next Steps <br />Congestion Analysis <br />The congestion analysis looks at traffic flow in the Northwest Twin Cities Metropolitan Area to <br />understand the extent, severity, duration and causes of congestion in the region. The analysis shows <br />that travelers regularly experience reduced speeds on highways in the Northwest Twin Cities Metro. <br />Analysis Highlights <br />Several of the major highways in the study area experience congestion: <br />• Interstate 94 <br />• Hwy10 <br />• Hwy 169 <br />• Hwy 101 <br />• Hwy 610 <br />Bottlenecks in each of the congested areas causes the congestion to extend upstream on the highway. <br />Upcoming projects have been identified for several of the congested areas and bottlenecks. These <br />include Hwy 10 grade separation projects through the cities of Anoka and Ramsey. <br />• <br />Congestion Analysis Measure <br />Severity — how slow does it get? <br />Duration — how long does it last? <br />Extent — how far does it reach? <br />Congestion in the Northwest Twin Cities Metro <br />Travelers encounter some form of congestion on several miles of highway in the Northwest Twin Cities <br />Metro area on a typical workday. The most intense morning congestion occurs around the Hwy 610 <br />and Hwy 252 interchange. There is also a stretch of heavy morning congestion on Hwy 169 between <br />Hwy 10 and the Mississippi River. Afternoon congestion follows a similar pattern, with the heaviest <br />congestion on Hwy 610 west of the Hwy 610 and Hwy 252 interchange and on northbound Hwy 169 <br />approaching the river. <br />See maps on next page for peak hour congestion and issues. <br />page 1 7 <br />
