This page contains a list of resources used to research and support information in Maryland state highway articles.
Highway Location Reference
[edit]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.
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.
Reference citations
[edit]{{Maryland HLR}} can be used to create citations to the HLR for one or multiple counties. Make sure to surround the template with <ref> tags and to enter a year and access date in addition to the specific county or counties.
HLR List
[edit]Maryland General Highway Statewide Grid Map
[edit]These maps, set at a scale of 1:12000, are the preferred two-dimensional resources for writing Route descriptions. They should be used in conjunction with the Highway Location Reference to write and support the Route description section of articles.
The following link leads to a map that allows selection by county. Within each of the county pages, there are links to the grid maps that cover the particular county.

[edit]{{Maryland grid map}} can be used to create citations to the current grid map. Make sure to surround the template with <ref> tags and enter grid section numbers.
Official state highway maps
[edit]The Maryland State Archives maintains as part of its Special Collections a State Highway Administration Map Collection. Series 2 of this special collection, referenced as MSA SC 4409, is a set of 68 maps that have been scanned and are available online. All maps are stored as PDF files and are password protected. Username is aaco and password is aaco#.
Included below are links to the information pages for each document. Maps may be accessed for downloading on their information pages. Notes are included with some maps explaining other relevant information about the map that could be useful.

State Roads Commission reports
[edit]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.
Included below are links to the information pages for each report. Reports may be downloaded in a variety of formats or read online. Next to the links are reference citation templates for each report to use in Wikipedia articles when referencing a particular report. Reference names include the final year addressed in a particular report. Finally, notes are included with many reports explaining other relevant information about the report that could be useful. When referencing these reports, be sure to add in the page or pages referenced and the date accessed in the citation template.

Construction Contract Log
[edit]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.
