  2. Review of traffic findings & recommendations • Bridge concepts • Alignments considerations • Next steps

  3. Traffic forecasting methodology • Traffic findings • Traffic recommendations

  4. Traffic Forecasting Methodology • Based on 2008 Counts as Baseline • Growth Based on ARC 2005 and 2030 Regional Model • Changes to Travel Patterns Based on ARC 2030 Model • Looks at Regional Flow of Traffic

  5. 2005 ADT on HBR ≈ 40,000 – 80,000 • 2030 ADT on HBR ≈ 50,000 – 100,000 • 30% increase in ADT until 2030 (Growth Rate ≈ 1.05 per year)

  6. Similar ADTs with 2 or 4 lane OAR • Location of bridge impacts ADT (north vs. south) • Design year traffic between 10 to 12K ADT • BCBR Does Not Attract More Thru Traffic • Serves as By-Pass to SR 400 Interchange • Local connectivity within Roswell (economic benefit) • Redistribution of intra-city traffic • Minor redistribution of regional traffic • Attracts minimal additional regional traffic

  7. Significant impact & cost • Impact to existing business • Cost to widen existing roadway & bridge • Does not support alternative modes • Attracts regional thru traffic • Provides less capacity (6 +2 > 8) • 8 lane ≈ 64,000 (at LOS D) • 6 lane plus 2 lane ≈ 69,000 (at LOS D) Recommendation #1Build Big Creek Bridge Road

  8. Traffic forecasts support 2 lane roadway • Other bridge crossings along SR 400 are 2 lanes • Minimize residential & environmental impacts • Consistent with Transportation Master Plan

  9. Small traffic increase if connected to Houze Rd • ADT Increase = 500 – 1,000 • Provides access to north & south • Connects to HBR at 3 locations • Warsaw Rd can accommodate additional ADT • Consistent with Transportation Master Plan • Reduce impacts to single family residential

  10. Build BCBR • 2 Lane BCBR • Terminate at Warsaw Road

  11. Create Sense of Place within bridge area • Invite Pedestrian and Bicycle Traffic • Remove SR 400 “Barrier” • Attractive View From BCBR and SR 400 • Ped/Bike =23 ft Car = 22 ft

  12. Aerial View From SR 400 View from Roadway Pedestrian View

  13. Alignment Considerations • Environmental • Neighborhood impacts • System connectivity • Access to public facilities • Development and redevelopment potential • Consistency with Roswell Transportation Master Plan

  14. Single Family Residences Wetlands & Streams Apartments Georgia Power Line Easement Townhomes & Apartments Big Creek Park New Townhomes Kimberly Clark Master Plan

  15. City Council direction/concurrence • Preferred Alternative(s) • Continued coordination • Inter-Departmental • External Stakeholders • Refine preferred alternative(s) • Finalize Environmental Screening • Preliminary ROW & Construction Cost Estimates • Develop programming and funding strategy • Limited traditional funding sources • Look at other funding sources • Final documentation for current phase

  16. Continued Coordination • City of Roswell Departments • Kimberly Clark • Apartment Complexes • Belcourt Apartments • Aspen Pointe Apartments • Roswell Creek Apartments • Public Meeting • Old Alabama Road Consultant Team • Other Stakeholders • NFCID • GDOT • ARC/SRTA/MARTA • City of Alpharetta
