US 36 Cor~rz~rx» Project No. NH 0361-070(7 X133) -' Mulfimodal One buffer-separated managed lane in each direction of U.S. 36 from Pecos Street to the Table Mesa/Foothills Parkway interchange. Maintain existing reversible managed lane operations on U.S. 36 from Pecos to Interstate 25. While this lane is open to High Occupancy Vehicles and Single Oacupancy Vehicle toll users, buses will have the highest priority, followed by HOV users. SOV toll and HOV use will be managed to ensure free flow conditions for bus travel. Access to the new managed lanes will have separate, at-grade buffer openings between each interchange for entering and exiting traffic. Highway • Ramp-to-Ramp auxiliary lanes for most segments of U.S. 36 from McCaslin Boulevard to I-25. • One new continuous eastbound general-purpose lane from Sheridan Boulevard to I-25. • One new climbing lane in each direction of U.S. 36 (westbound begins at McCaslin Boulevard; eastbound begins at Table Mesa) to the top of Davidson Mesa. Bikeway • Adopt the west-end corridor alignment identified as the 'US 36 Bikeway Option' in the Draft EIS public comments, which places the bikeway along the south side of the highway from Table Mesa to South Boulder Creek before traveling along the north side of U.S. 36 to McCaslin Boulevard. • From McCaslin to Sheridan, the bikeway aligns along the north side of the highway from McCaslin to Coal Creek, crosses to the south side of the highway and follows an access road under U.S. 36 to cross to the north side to Flatirons West, before returning along the south side through Broomfield. • From Sheridan Boulevard to Broadway, the bikeway remains on the south side of US 36 until Bradburn Boulevard, then travels south on Bradburn to 72nd Avenue, where it connects to the Little Dry Creek Trail. • Grade-separated bike crossings will be incorporated as interchanges are rebuilt. Additional connections to streets, trails and new developments also would be encouraged and supported as appropriate. Additional Analysis Recognizing that this alternative will undergo additional analysis to verify consistency with the project's purpose and need, design and safety standards, financial feasibility, regulatory requirements and local municipality requests, the PAC recognizes that additional refinements may be necessary prior to declaring this alternative as the Preferred for the FEIS: • Develop traffic simulation model at select locations across the corridor. • Evaluate and consider impacts of combined alternative on local arterials and other resources identified in DEIS. • Examine feasibility of aligning U.S. 36 bikeway along the south side of highway from Sheridan Boulevard to Broadway Boulevard provided there are no additional right-of-way takes. • Evaluate the benefit, cost and impacts of an 88th Street drop ramp to the managed lanes and local roads to improve access to and from the municipalities of Louisville and Superior. • Examine design refinements at Table Mesa to improve transit operations. • Evaluate inclusion of a Broadway slip ramp from southbound I-25 to westbound U.S. 36. • Examine additional measures to reduce right-of-way impacts. • Evaluate ramp volumes from Sheridan Boulevard to I-25. • Evaluate water quality and conveyance from US 36 and opportunities to partner with jurisdictions to address problem areas.
