<br /> <br />3.2. 2040 Future Roadway Capacity Improvement Needs <br />To identify the need for potential future capacity improvements, Metropolitan Council 2040 <br />forecasts were compared to planning-level roadway capacities for Principal and A-Minor <br />Arterial Roadways. Planning-level roadway capacities used for this analysis are illustrated in <br /> below. Based on this comparison, most roadways in the city have adequate capacity to <br />Table 6 <br />accommodate forecasted Metropolitan Council 2040 travel volumes with little to minimal <br />congestion. These roadways are expected to function well through the 2040 planning horizon. <br />Table 6: Planning-Level Roadway Capacity <br />Daily Two-way Volume <br />Lower Higher <br />Facility Type Threshold Threshold <br />Two-lane Undivided 10,000 12,000 <br />Two-lane Divided or Three-lane Undivided 15,000 17,000 <br />Arterials <br />Four-lane Undivided 18,000 22,000 <br />Four-lane Divided or Five-lane Undivided 28,000 32,000 <br />Four-lane Freeway 60,000 80,000 <br />Six-lane Freeway 90,000 120,000 <br />Freeways <br />Calculated on a <br />Eight-lane Freeway or Higher <br />segment-by-segment basis <br />Based on these planning level roadway capacities, portions of TH 47, US 10, Armstrong <br />Boulevard (CSAH 83), and Ramsey Boulevard (CSAH 56) are expected to exceed capacity in <br />2040. TH 47 is currently a rural two-lane roadway with a planning-level capacity of 10,000 <br />12,000 and a forecasted 2040 volume of 9,50022,200. US 10 is a four-lane divided roadway with <br />a planning-level capacity of 28,00032,000 and a forecasted 2040 volume of 44,00067,000. <br />Armstrong Boulevard (CSAH 83) and Ramsey Boulevard (CSAH 56) each vary between two <br />and four lanes within Ramsey, but each roadway includes a segment where the forecasted 2040 <br />volume would surpass the associated planning-level capacity for a two-lane undivided <br />roadway of 10,00012,000 (15,300 for Armstrong Boulevard and 14,100 for Ramsey Boulevard). <br />Accordingly, motorists will likely experience some congestion along these roadways during the <br />2040 planning horizon. <br /> <br /> <br /> <br /> <br /> <br />Chapter 5 Transportation (DRAFT) Page X-24 <br />Adopted XXXXXX XX, 2017 <br /> <br />
