• Abstract:
  The main objectives of this study were to propose warranting conditions, to identify operational considerations and to prepare implementation guidelines for the development of flyovers. This has been accomplished. Also, it has been demonstrated that flyovers can increase the capacity of congested arterial intersections in a cost-effective manner. A relationship has been developed between average approach volume over the design life of the project and benefits. Projects with an average approach volume of 50,000 vehicles per day generate benefits of $6.5 million which is greater than typical costs of about $5 million dollars. Implementation of several flyovers in Texas would be appropriate to substantiate their benefits and provide an impetus for further use of the concept.
