What are Managed Lanes?

Managed lanes (MLs) also known as express lanes, TEXpress lanes are tolled lanes

that offer variable alternatives to single-occupant vehicle (SOV) use and increase

throughput using variable pricing, which ensure free-flow service.

Does Managed Lanes take away existing General Purpose Lanes?

No. Managed lanes (MLs) are additional capacities added to the existing corridor.

RTC Policy and State Law do not allow free lanes to be converted to tolled lanes.

2. Southern Gateway Project History

Began in 2001 as a Major Investment Study, Schematic, and Environmental Assessment (EA) Study limits

o IH 35E from IH 20 to 8th St. (8.6 miles)

o US 67 from FM 1382 to IH 35E (9.4 miles)

Southern Gateway Total Reconstruction Project Original Scopes;

o Total Reconstructiono Additional General Purpose (GP) capacity

o Reversible HOV in center median

o Slip ramps, direct connect ramps, frontage roads, and x-streets

Fully directional interchanges at IH 20 for IH 35E and US 67

Estimated Cost of Total Reconstruction of IH 35E and US 67 - $2 Billion

Policy, staff and community work groups held on regular basis

Five-day Value Engineering (VE) Study completed

Public Involvement

o Three series of public meetings

o Three newsletterso Aesthetics Concept Plan

o Project website (www.thesoutherngateway.org)

o Series of public hearings were held in August 2005

Finding of No Significant Impact (FONSI) obtained June 2006

2. Project Overview

Managed Lanes Project

Focus on reconstruction of IH 35E from north of the IH 35E/US 67 split to Colorado Blvd.

Improve safety by flattening the Zang Curve on IH 35E

Add managed lane capacity south of the IH35E/US67 split utilizing existing pavement.

During the 83rd Legislature, the Southern Gateway project was granted the authority tobe developed as a Public-Private Partnership project. The project is proceeding with theintent to develop the partnerships and a financial package for a procurement that istentatively expected to be complete during the 84th Legislature in 2015.

2. Project Overview

TSG Goals

Improve mobility in Southern DallasCounty

Improve safety on IH 35E and US 67

Bring dilapidated facility condition up tocurrent standards.

Minimize negative EnvironmentalImpacts

Provide affordable, cost effectivetransportation solutions


Provide uniform connectivity with adjacent projects such as the Horseshoe Identify options for delivery of the ultimate corridor improvements Utilize public private partnership delivery to accelerate scheduled

improvements Identify long term delivery options. Provide a design that is sensitive to needs of different neighborhoods,

promote walkable & bicycle communities by ensuring that major cross streetsat frontage roads include crosswalks and wide outside share lanes.
