text: After US 29's arrival in 1934, MD 27 and MD 29 swapped numbers; today's MD 27 received its current designation and did not physically change, while the original MD 27 was re-designated MD 29, and then immediately promoted to US 29, thus removing a conflict between the US highway number and the state highway number system, as AASHO prohibits number duplication between state and US route systems.
