The advantage of prestressed concrete deck bulb tee (DBT) girder bridges is the speed of construction, since no separate decking is required. However, the performance of the connection between girders has been a primary concern.

The TRB National Cooperative Highway Research Program's NCHRP Research Report 999: Design and Construction of Deck Bulb Tee Girder Bridges with UHPC Connections presents an evaluation of prestressed concrete DBT girder bridges with ultrahigh-performance concrete (UHPC) connections.
