Houston I-45 Parkway & Tunnel Concept / Before & After
Picture of downtown Houston and I-45 taken south of North Main Street. Instead of widening I-45 the proposed parkway/tunnel concept calls for placing I-45 underground in two tunnels and to reconstruct the existing at-grade I-45 into a parkway with high capacity transit in the middle. (Place the cursor over the picture to see the transformation.)
