MD 90 begins at a partial directional interchange with US 50 (Ocean Gateway) east of Whaleyville. There is no access from westbound MD 90 to eastbound US 50 or from westbound US 50 to eastbound MD 90. MD 90 heads east as a two-lane undivided freeway with rumble strips within the painted median. Headlight use is required at all times. After passing under MD 346 (Old Ocean City Boulevard) with no access, the state highway crosses over Church Branch. MD 90 comes to a bridge over the Snow Hill Line of the Maryland and Delaware Railroad before reaching a partial cloverleaf interchange with US 113 (Worcester Highway). After passing over MD 575 (Worcester Highway), the old alignment of US 113, with no access, the state highway becomes divided with a narrow guardrail median barrier.
