Check for the Approved for Publication date
Individual Standard Plans may vary in content over time and are distinguished by the "Approved for Publication" date in the lower right corner of the plan. This date authorizes the plan's use in project design thereafter, but before that plan may be referred to in a set of contract provisions and plans, it must be listed in the "Standard Plans" General Special Provision (GSP), with its approval date, and be issued in the respective manual: Standard Plans for Road, Bridge and Municipal Construction M 21-01.
Individual Standard Plans Manuals vary regularly over time (scheduled for revision roughly every 12 months) and are identified by an Effective date, shown at the bottom of the Contents pages in the manual. The provisions of a contract indicate which Manual is valid for that contract by citing the Effective date. It also lists the plans with their approval dates, analogous to that Manual's table of contents (view current GSP).
Approved for Publication Date vs Effective Date
The "Approved for Publication" date applies to an individual Standard Plan, whereas the "Effective" date applies to a Standard Plans Manual publication. One should expect an individual Standard Plan to appear in several consecutive Manuals, i.e. that the same "Approved for Publication" date persists through several Effective date ranges.
The links below download Adobe Acrobat files of Standard Plans Manuals in effect between the dates listed, with the first date of each entry being the Effective date as indicated in the "Standard Plans" General Special Provision of a contract. One should be careful to note any addenda which may indicate a different date.
