CITIZENS TASK FORCE CONCEPTSFOR SOUTHERN GATEWAY

TWO CONCEPTS - ONE PROJECT

Klyde Warren Park ModelCentral Expressway Model

• Our concept for the Southern Gateway uses two already successful models within the city of Dallas

• The Central Expressway Model of building below grade.

• The Klyde Warren Park Model of decking across the below grade highway.

HISTORY OF I-35E

Dallas Zoo

This picture was taken in August 1959, just before the Dallas Zoo was cut off from the core of Oak Cliff. The view is looking south from Marsalis Avenue. Notice the existing residential communities directly in the path of the Interstate

HISTORY OF I-35E

This photo was taken just over a year later in October 1960. The highway’s path through Oak Cliff including the present day Zang Curve has been cleared of homes and businesses prior to construction.

HOW CAN WE DO BETTER?

Focus on key improvements to the Southern Gateway Design• Improved traffic flow and safety measures

• Protection against noise and air pollution

• Better information to drivers

• Minimizing the ROW of the project

• Reconnecting the community

IMPROVING TRAFFIC FLOW AND SAFETY

• Combine the southbound 12th Street exit with the exit for Marsalis Avenue

• Combine the northbound exit for Beckley/Overton Road with the Loop 12/Ann Arbor exit using existing ROW to extend the frontage road

• Continue to prohibit hazardous cargo

• Provide at least 2 continuous lanes between I-20 and I-30

• Provide a continuous usable shoulder throughout entire length of project

• No thru-lanes should become exit-only lanes

• Provide raised reflective lane marker buttons instead of stripes

PROTECTION AGAINST NOISE AND AIR POLLUTION

• Provide acoustic pavement the entire length of the highway

• Put the Oak back in Oak Cliff with massive tree plantings along the highway

• Prohibit loud braking by trucks

• Provide acoustic walls a minimum of 8 feet high for residential neighborhoods

PROVIDE BETTER INFORMATION TO DRIVERS

• Provide fewer signs but with clearer messages along the highway

• No new advertisement signage on residential portions of the highway

• Change the electronic signage to provide alternative routes instead of just travel time using a single route

Examples for NB US-67

MINIMIZING ROW

• Use the Central Expressway model and put the highway below grade

• Having the highway below grade is a must between Clarendon and 8th street

• Cantilever the frontage roads over the main lanes of the highway

• Cantilever the main lanes over the managed lanes to minimize ROW in the Zang Curve

• It must be below grade from Clarendon to 8th St. at a minimum

• If you can do it for North Dallas you can do for Oak Cliff

RECONNECTING NEIGHBORHOODS

• Provide numerous pedestrian connections and crossovers at neighborhoods such as Beckley Club, Beckleywood, Ruthmeade Place, and Oak Park Estates

• Use the Klyde Warren Park Model and deck over I-35 between Ewing and Beckley to reconnect the Dallas Zoo with the core of Oak Cliff
