Traffic Volumes - Existing 190,000 vpd 80,000 vpd 100,000 vpd 60,000 vpd 120,000 vpd vpd: vehicles per day
Freeway Accidents 379 accidents/year 180 accidents/year 119 accidents/year 68 accidents/year These accident rates are similar to the regional averages. Note: Average reported accidents per year, 1997-1999
Population and Employment Growth Metropolitan Planning Area % 1999 2025 Change Population 4,536,000 6,671,000 47 % Employment 2,691,000 3,907,400 45 % Note: The Metropolitan Planning Area consists of Dallas, Collin, Tarrant, Denton, Rockwall Counties and parts of Ellis, Johnson, Parker, Kaufman Counties

Traffic Volumes - 2025 Total Demand 340,000 vpd 180,000 vpd 140,000 vpd 170,000 vpd 150,000 vpd vpd: vehicles per day
Traffic Volumes - Existing and 2025 Demand 1999: 190,000 vpd 2025: 340,000 vpd 1999: 80,000 vpd 2025: 180,000 vpd 1999: 100,000 vpd 2025: 140,000 vpd 1999: 60,000 vpd 2025: 170,000 vpd 1999: 120,000 vpd 2025: 150,000 vpd vpd: vehicles per day
Freeway and HOV Alternatives • Demand exceeds what can be accommodated using non-freeway alternatives • Mobility focus is on moving people, not necessarily vehicles • HOV alternatives provide additional person-capacity • Freeway/HOV alternatives constrained by adjacent land uses - minimize or eliminate ROW impacts

Freeway and HOV Alternatives IH 35E North, North of Marsalis IH 35E North, South of Marsalis US 67 North IH 35E South US 67 South
Transportation SYSTEM IH 35E North Project Pegasus/ Trinity Parkway
IH 35E North - Alternatives • No-Build • Freeway General Purpose Lanes - 4 in each direction - 5 in each direction - 6 in each direction • HOV or Special Use Lanes - None - 1 in each direction - 1 reversible - 2 reversible - 3 reversible • At-Grade and Elevated were considered
IH 35E North – Draft Preferred Alternative 5 Mainlanes + 2 Reversible Lanes + 5 Mainlanes
IH 35E South - Alternatives • No-Build • Freeway General Purpose Lanes - 3 in each direction - 4 in each direction • HOV or Special Use Lanes - None - 1 in each direction - 1 reversible - 2 reversible • At-Grade and Elevated were considered
IH 35E South – Draft Preferred Alternative 3 Mainlanes + 1 Reversible Lane + 3 Mainlanes
US 67 North - Alternatives • No-Build • Freeway General Purpose Lanes - 2 in each direction - 3 in each direction - 4 in each direction • HOV or Special Use Lanes - None - 1 in each direction - 1 reversible - 2 reversible • At-Grade and Elevated were considered
US 67 North – Draft Preferred Alternative 3 Mainlanes + 2 Reversible Lanes + 3 Mainlanes
US 67 South - Alternatives • No-Build • Freeway General Purpose Lanes - 2 in each direction - 3 in each direction - 4 in each direction • HOV or Special Use Lanes - None - 1 in each direction - 1 reversible - 2 reversible • At-Grade and Elevated were considered
US 67 South – Draft Preferred Alternative 3 Mainlanes + 1 Reversible Lane + 3 Mainlanes
New Frontage Roads? • Existing frontage roads will not be removed • No existing frontage roads from 12th Street to Saner • Should new frontage roads be added? • Do the benefits outweigh the costs?
Frontage RoadsBenefits and Costs Note: This analysis is limited to IH 35E from 12th Street to Saner
New Frontage Roads? Recommendation New frontage roads should not be constructed between 12th Street and Saner.
Design Standards • Design Standards have changed over time- Inadequate vertical clearances- Inadequate lane and shoulder widths- Substandard ramps and merge lanes- Tight curves on freeway lanes- Problems primarily on IH 35E North segment
Preferred AlternativePresentations • Cities- Dallas - Cedar Hill - DeSoto - Duncanville - Lancaster • Dallas County • DART • North Texas Tollway Authority • NCTCOG These presentations will take place over the next two to four months and the Work Groups will be briefed on the presentations at future meetings.
