Description: Provide complete design services for the reconstruction of the I-20/I-520 system-to-system interchange. Includes Davis Road widening, I-20 widening, and Crane's Creek.

Significant Facts:
  • The challenge was designing a new interchange in an already developed urban area. Construction staging and maintenance of traffic were very complex.
  • All available land area was used to create a series of detention ponds, resulting in a significant reduction in peak flows of Crane's Creek.
