quick_answer: Quick answer: I-30 is the shortest Dallas–Fort Worth route (~32 miles, ~30 minutes clear). It is not always the fastest. Take I-20 (~40 miles) on Cowboys, Rangers, or Six Flags days and whenever I-30 has an incident. Timing still beats routing: route spread is about 10–15 minutes; departure-time spread is about 30+.

faqs[5]{q,a}:
  What is the fastest route from Dallas to Fort Worth?,I-30 is shortest (~32 miles, ~30 minutes free-flow) and usually fastest off-peak. I-20 (~40 miles) often wins on event days and I-30 incidents. SH 183/121 wins only when either end already sits on the northern/airport corridor.
  When does the longer route win?,When I-30 is congested. Eight extra miles at highway speed beat fewer miles at 20 mph. Take I-20 for AT&T Stadium, Globe Life Field, or Six Flags peak days, and whenever an incident is reported on I-30.
  Is I-30 TEXpress worth it?,You are buying variance reduction, not a guaranteed faster trip. Managed lanes stay moderately fast when free lanes collapse. For a routine commute, a better departure time is usually cheaper than the toll.
  Does route choice matter more than departure time?,No. Route spread at a given hour is typically 10–15 minutes. Departure-time spread on a given route is typically 30+. Optimize when you leave first, then pick the road that is actually moving.
  How should I choose on the day?,Event in Arlington → I-20. Incident on I-30 → I-20. Either end near Irving / Las Colinas / the airport highway → SH 183/121. Friday 4:00–6:30 p.m. → I-20 or leave earlier. Otherwise I-30.
