Summary: For this project, ADOT&PF is planning to realign the Glenn Highway between MP 53 and MP 56. A bridge type study was conducted, and the following design alternatives were evaluated:
- Precast, prestressed concrete decked bulb-tee;
- Steel plate girder with concrete deck;
- Trapezoidal steel box girder with concrete deck; and
- Cast-in-place, post-tensioned concrete box girder.
Each alternative was evaluated for estimated cost, design criteria satisfaction, and construction methodology to determine the most feasible bridge type for this project.
