In this design-build project, PacRim Engineering served as the independent design checker for the C5 Venice/Robertson aerial structure. The Mid-City/Exposition LRT line extended approximately 8.6 miles from downtown Los Angeles to Culver City. The C5 Venice/Robertson Aerial Structure was one of the most complex segments of the line. The proposed aerial overcrossing structure consisted of fourteen spans with each span ranging from approximately 93 to 167 feet long and supported by an abutment at the eastern end and fourteen bents. The proposed overcrossing consisted of three segments: 1) Bents 2 through 6: the overcrossing was a superstructure supported by a single column; 2) Bents 7 through 11: the overcrossing was separated into two superstructures and each structure is supported by a single column; and, 3) Bents 12 through 15: the overcrossing became a superstructure supported by two columns.
