Wikipedia:WikiProject U.S. Roads/Maryland/Resources#HLR List

The Maryland State Highway Administration produces a Highway Location Reference (HLR) for each county annually since 1999. Each HLR contains a stylized map showing highways in that county, a list changes in state highways that occurred in that county during the year of the HLR, a list of routes that are part of the National Highway System, and detailed, mileposted information about intersections, bridges, road widths and lane sections, maintenance jurisdiction, and for all Interstate, U.S., and Maryland state-numbered highways with that county.

• [https://www.roads.maryland.gov/mdotsha/pages/Index.aspx?PageId=832 Highway Location Reference at the MDSHA website]

The table below contains links to every HLR published on the MDSHA website from 1999 onwards. The HLRs should be used to source and reference all mileage numbers in Maryland state highway articles. The HLRs are also very useful in writing the Route description and Junction list of an article. Whenever you update an article, please check to make sure the most recent HLR is being referenced.

{{tl|Maryland HLR}} can be used to create citations to the HLR for one or multiple counties. Make sure to surround the template with tags and to enter a year and access date in addition to the specific county or counties.

The Internet Archive contains a set of reports of the Maryland State Roads Commission, the predecessor agency of the Maryland State Highway Administration. These reports, which were scanned and uploaded in August 2009 by the University of Maryland, College Park, contain information about the processes and works of the SRC for a particular set of years. The reports are very helpful to determine when particular roads and bridges were constructed and understanding the context surrounding their planning and construction.

These documents are spreadsheets listing construction projects in each county, including their start and end dates, from the 1940s to the 2000s. The first document also features a list of road opening dates, a list of divided or controlled-access highways as of 1960, and fact sheets on the Chesapeake Bay Bridge and Baltimore Harbor Tunnel. The first (1947–1984) and third (1983–2006) documents together feature the whole range, but the split varies between 1966 and 1984 depending on the county. The second document is entirely redundant with the other two.
