  2. 42nd Street Event Traffic Management Final Alternatives After Canad is open and operating generating different traffic patterns

  3. Alternatives Not Recommended • Additional On-Site Parking – due to cost and infrequent use • Additional parking for adjacent developments should have shared arrangements • Construct 17th Ave S. Overpass – Too much misdirection for cost • Still needed in future • Direct Access to I-29 – Against FHWA policy • Access point would be 17th Ave S.

  4. South Lot takes 88 Minutes to Empty

  5. South Lot takes 57 Minutes to Empty

  6. Build 43/Extend 17th South Lot takes 45 Minutes to Empty

  7. South Lot takes 38 Minutes to Empty

  8. Table 1 Event Departure Alternatives A A All alternatives are also represented in Figures 1-4. B The percent reduction is calculated separately for the exit direction and is the time reduction for the direction using the highest exit times. C The weighted average exit time is calculated weighting the number of vehicles and the average time in takes each to exit, assuming the average departure time per vehicle is half of the longest exit time. (1) Typically, during an event that is at capacity, traffic departing from Lot 3 and the VIP lot are directed half to the north and half to the south on 42nd Street. (2) Assumes that the center left-turn lane that is temporarily used as a thru lane will only achieve 600 vph, thru lanes achieve 900 vph. Number of lanes per rate is shown in parenthesis. (3) Relates to actual observations or testimony (Backstreet Boys 71 minutes) (4) This reduction in exit time is a function of the reduced number of spaces in the north lot. It is not due to increased efficiency. (5) Assumes 225 vehicles from the VIP lot and 350 vehicles from the south parking lot (see Figure 4)

  9. Build 43/Extend 17th South Lot takes 45 Minutes to Empty Recommending this Alternative Cost ~ $0.5 M plus expand 38/32

  10. Add Turn Lanes May need to Capture Through as Left Intersection of 32nd & 38th
