STATION 1:  WELCOME

At this station, you can:

 

STATION 2:  STUDY APPROACH

At this station, you can:

  • Review the Study Approach to get information on the study process
  • Review the I-345 Project Timeline to understand the overall timeline and next steps
  • View the Study Goals for both City Map and the I-345 Feasibility Study

 

STATION 3:  ENVIRONMENTAL

At this station, you can:

  • View the environmental constraints map which helps planners and engineers determine the least impactful method to fulfill the purpose of the project. 

 

STATION 4:  CONCEPTUAL ALTERNATIVES

At this station, you can:

  • View information on each of the 5 alternatives to help you better understand and visualize what is being proposed.
  • Each alternative includes typical sections, a conceptual rendering and a roll plot with design details.
  • No Build/Leave I-345 As-Is:  No additional improvements would occur to I-345 other than those already programmed.
  • Depressed Alternative:  Similar to US 75, where mainlanes are low (below DART D2) with discontinuous frontage roads along either side and cross streets over the top.  Includes pedestrian and bicycle facilities along the frontage roads and local streets.
  • Removal Alternative:  The existing mainlanes would be removed and the city grid is reconnected.  Includes pedestrian and bicycle facilities.
  • Elevated Alternative:  Similar to what exists now, with a smaller footprint of an elevated highway with aesthetic improvements, revised access and signage for drivers, and pedestrian and bicycle facilities under the highway.
  • Hybrid Alternative:  Similar to US 75 and the proposed depressed alternative.  There is limited access from the mainlanes to local streets that are reconnected over the top.  No proposed frontage roads.  Access to the area is from local streets, I-30 or Woodall Rodgers Freeway.  Includes pedestrian and bicycle facilities along local streets.
  • View roll plots
