In December 2008, the Maryland Transportation Authority began a project to replace MD 24's intersection with MD 924 and Tollgate Road just north of the MD 24 – I-95 interchange. The intersection was replaced with a diamond interchange in October 2011. As part of the project, the MD 24 – I-95 interchange had several ramps altered to separate I-95 traffic heading for MD 24 and MD 924. The Maryland State Highway Administration has long-term plans to expand the Bel Air Bypass to a divided highway from Winters Run to US 1 Business south of Hickory. The Bel Air Bypass is already a four-lane divided highway between MD 147 and Winters Run and around Hickory, but is a three- to four-lane undivided highway from Winters Run to US 1 Business south of Hickory. The Bel Air Bypass would be expanded to a four-lane divided highway from Winters Run to MD 24 and a six-lane divided highway along the US 1 – MD 24 concurrency. The US 1 – MD 24 intersection would be reconstructed as a trumpet interchange. The planning phase of the project was completed in 2001, but engineering, right-of-way acquisition, and actual construction are on hold until funding becomes available.
