In September 2021, the Maryland Transit Administration (MTA) announced the installation of a new mural project at Penn-North station painted by Baltimore artist Megan Lewis on a $60,000 commission.

The underlying geology consists of the crystalline metamorphic rocks and their derivatives which are characteristic of the Piedmont physiographic region which contacts Cretaceous sedimentary formations along the diagonal Fall Line in Baltimore.

[5] The excavation for Penn-North station was supported by soldier piles anchored in the earth beneath it; extending through soil up to 50 feet below street level and through rock at greater depths.

The area around Penn-North station at the time of excavation included two-story residential rowhouses two- to three-story warehouse-type buildings.

0.14 feet of settlement was measured and attributed to gradual groundwater drawdown which occurred during the excavation, resulting in deep-seated lateral movements which caused little observable distress on the overlying structures.
