Freeway and HOV Freeway and HOV AlternativesAlternatives
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

New Frontage Roads?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?
Public Meetings - November 18 & 21, 2002
Frontage RoadsFrontage RoadsBenefits and CostsBenefits and Costs
Benefits CommentsAccess All existing properties have access from
existing road network.Ramp options Limited number of ramps in area needed.Alternative route during incidents
Zang and Beckley provide this on either side of the freeway.
Costs CommentsROW Impacts Existing ROW will not accommodate new
frontage roads in most locations.Construction Costs
New frontage roads would require extensive retaining walls and bridge structures over creek and DART rail.
Note: This analysis is limited to IH 35E from 12th Street to Saner
Public Meetings - November 18 & 21, 2002
New Frontage Roads?New Frontage Roads?
Recommendation
New frontage roads should not be constructed between 12th Street and Saner.
Public Meetings - November 18 & 21, 2002
Design StandardsDesign 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
