MnDOT Transportation Asset Management Plan

Asset Management is a systematic process of maintaining, upgrading and operating physical assets cost-effectively throughout their life-cycle.


On July 6, 2012, the Moving Ahead for Progress in the 21st Century Act was signed into law. MAP-21 required states to develop a risk-based Transportation Asset Management Plan for the National Highway System to improve and preserve the condition of the assets and the performance of the system. The legislation focused on the development of a TAMP for bridges and pavements on the NHS, but encouraged states to include other infrastructure assets within the right-of-way corridor. These requirements were continued in the Fixing America’s Surface Transportation Act, enacted in 2015.

After the requirements for the TAMP were established in MAP-21, MnDOT was selected as one of three pilot states to develop its first ever draft TAMP. The draft was completed in 2014, included four additional assets beyond pavement and bridge, and was shared publicly to help other states develop their TAMPs. Since then, MnDOT has expanded the number of assets included in asset management planning and made significant progress on the priority strategies in the draft. The final TAMP 2019 includes the work completed during the initial pilot project as well as subsequent additions and refinements and has received full certification from the Federal Highway Administration.

The TAMP 2019 contains the following twelve of many MnDOT-owned asset classes: pavements, bridges, culverts, deep storm water tunnels, overhead sign structures, high-mast light tower structures, noise walls, signals, lighting, pedestrian infrastructure, buildings, and intelligent transportation systems. It further serves as an accountability and communication tool to inform established capital and operations planning efforts.
