"Off-label." Good one. 😃 The WC's map shows that Elm Street was just as wide as Main Street and connected directly to Stemmons Freeway. Those two turns were NOT needed. End of story.
Here is CE2113:
In it, The entrance/exit ramps on Stemmons are as wide as the through carriageways, and the Stemmons carriageways are significantly narrower than Elm, Main and Commerce. BTW, the Stemmons carriageways were originally built to be 5 lanes wide, see the following:
For that matter Austin and Market are significantly narrower than Houston and Lamar, not that CE2113 knows that.
CE2113 is just not a to-scale representation of the West End. It's simply foolish to rely on it as if it were.
