This website is intended to assist in the checking and review of Highway Design Plans. It is currently under development with new routines being created and others being tested.

One of the key features is that the user can input their known data and the software will attempt to calculate the unknowns. But such a feature has inherent risks because multiple user inputs may conflict. Because the data provided isn't overwritten, care must be used during data input. Please use at your own risk.

Another helpful feature is the creation of DXF files for horizontal and vertical alignments, station-offsets, traverses and superelevation diagrams. These DXF files can be imported into Cadd for easier review and plotting. Example input files are available at Notes > Example Files.

For comments and suggestions please send feedback.
