HOW CAN WE DO BETTER?

Focus on key improvements to the SouthernGateway 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 SAFET

• 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 existingROW to extend the frontage road

• Continue to prohibit hazardous cargo

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

• Provide a continuous usable shoulder throughoutentire length of project

• No thru-lanes should become exit-only lanes

• Provide raised reflective lane marker buttons insteadof stripes



PROTECTION AGAINST NOISE AND AIR POLLUT

• Provide acoustic pavement the

entire length of the highway

• Put the Oak back in Oak Cliff withmassive tree plantings along thehighway

• Prohibit loud braking by trucks

• Provide acoustic walls a minimum

of 8 feet high for residentialneighborhoods



PROVIDE BETTER INFORMATION TO DRIVE

• 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 otravel time using a single route

Travel Time to I-35E & Inwood Road:

Via I-35E 26minVia Hampton Rd 28min

Travel Time to I-35E & Wycliff Ave:Via Polk St 21minVia I-35E 23min

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 mainlanes 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 asBeckley Club, Beckleywood, RuthmeadePlace, and Oak Park Estates

• Use the Klyde Warren Park Model and deckover I-35 between Ewing and Beckley toreconnect the Dallas Zoo with the core ofOak Cliff
