Corridor Analysis identified the following:

MAN-MADE FEATURES

Major Roadway Interchanges

Underpass and Overpass Conditions

DART Interface

Airport Interface

NATURAL FEATURES

Creek Crossings

POLITICAL BOUNDARIES

City Limits

2003 District Identifier

Corridor Aesthetics

Developed distinctive markers for each of the five neighborhoods and city districts:

DeSoto/Lancaster

Cedar Hill/Duncanville

Southeast Oak Cliff

Southwest Oak Cliff

Oak Cliff The objective is to maintain structural consistency of hardscape elements throughout the length of the corridor. DISTRICT IDENTIFIER

2003 Thematic Design

Corridor Aesthetics

The urban design of the Southern Gateway corridor evolved from the site analysis process that considered the adjacent neighborhood character of the corridor beginning in the suburban areas of Lancaster and Cedar Hill and continuing through many diverse neighborhoods to the urban center of Oak Cliff. The design took the area’s rolling hills, mature trees and exposed native limestone into consideration. The limestone geology, or strata, established the corridor theme and was interpreted through pattern in the hardscape design elements of the corridor.

Corridor Aesthetics Technical Guidelines

Next Steps

Corridor Aesthetics

1. TxDOT Finalizes Draft Aesthetic Guidelines and initiates Design-Build Project • Segment 1 (IH-35E) – Full Reconstruction, full implementation of guidelines • Segment 2A (US 67) – Widening of existing, partial implementation of

guidelines o Full implementation of guidelines for proposed Noise Walls o Widening of existing bridges along with retaining walls will receive In

Kind aesthetic implementation

2. City of Dallas/Stakeholders develop standalone aesthetic/landscaping enhancement projects 3. Projects submitted for funding:

• TxDOT Green Ribbon Landscape Improvements Program • Other

4. City of Dallas design, construction and maintenance of enhancement projects
