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?


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


New Frontage Roads?New Frontage Roads?

Recommendation

New frontage roads should not be constructed between 12th Street and Saner.


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
