Detailed Drawings
The Detailed Drawings have been updated in their entirety effective with the September 11, 2014 bid letting. The new drawings contain both
metric and English dimensions. This has eliminated the need for a separate English or metric version of each drawing. Numerous other
changes have been made with this release. Users are encouraged to review the new drawings prior to bidding or construction. Hard copies
are available for purchase from the Contract Plans Bureau, 406-444-6215 or .

All drawings are available on the MDT website here: DETAILED DRAWINGS

Section 501, PCCP details.
Section 606, Barrier rail concrete and connections.

The Detailed Drawings contain a mixture of 8 X 11 and 11 X 17 sheets. If a hard copy is ordered, the user will need to hand collate the
drawings in the correct order. Our printing process does not allow for an automated collating of the different sized sheets.
