Highway Pavement and Bridge Conditions

The final rule for highway pavement condition and bridge condition was published on January 18, 2017. The effective date of the rule has been postponed (to May 20, 2017). Per the final rule, targets must be established by State DOTs in February 2018, and the TPB would set targets within 180 days, or August 2018.

The companion highway asset management plan rule is final. The State DOTs are working on their asset management plans which will inform future planning of highway and bridge preservation projects.

TPB staff completed an analysis of the region’s 2015 Bridge and Pavement data, available through  the National Bridge Inventory (NBI) and the Highway Performance Monitoring System (HPMS).  Results for the region were presented at the December 2, 2016 Technical Committee meeting.

TPB staff completed an updated analysis for local jurisdiction in March 2017, after the 2016 bridge data became available in January 2017. A one-page summary sheet was developed to report the pavement and bridge conditions in each jurisdiction. In addition to showing the required performance measures (good and poor condition), the summary sheet also provides background information such as lane-miles of Interstate and Non-Interstate NHS, the top 3 deficient bridges, and ownership of the Non-Interstate NHS. This information has been aggregated for the TPB planning area, but is also provided for Suburban Maryland and Northern Virginia and for each jurisdiction in the region.

A map site for the current pavement and bridge conditions has been developed: 

In addition to the map site, staff are updating the Regional Data Clearinghouse to provide data files and GIS layers for use by any interested party.
