|TSL's are drawings that depict the general type and size of a bridge,
its location and the proposed work to be done. TSL drawings are done by
the Bureau of Bridges and Structures Planning Unit or by the consultant.
IDOT consultants, contractors, fabricators and suppliers may benefit
from being able to preview the type of bridges and materials to be used
on future projects. Final bridge types, material and details are subject
to refinement during the design phase.
The following TSL drawings are in Adobe PDF format. These drawings
are for bridge projects on the State Highway System that have been
approved for design. This list will be updated every 3 months and
projects will be removed from the list after they have been awarded.
