Allen, McKinney launch 121 North branding for SH 121 corridor

Allen and McKinney have put a name on the stretch of State Highway 121 between them, but the real test of 121 North will be whether the branding pulls employers, investment and higher-value development into a corridor that already has momentum. The May launch by the two cities’ economic development corporations is meant to give the highway a clearer identity, one that can help shape where companies look first in Collin County and how investors think about the next wave of North Texas growth.

Allen is leaning on a development pipeline that already reaches well beyond a slogan. The city says it has more than 9 million square feet of Class A office planned in modern mixed-use projects, led by Sloan Corners and The Farm in Allen. Sloan Corners, a 261-acre project at US 75 and SH 121, is planned for more than 6 million square feet of Class A office space. The Farm, a 135-acre development that broke ground in 2021, is planned to include more than 1.6 million square feet of office space, along with retail, a hotel, homes and trails.

The corridor is not theoretical. FarmWorks One, a 102,000-square-foot Class A office building in The Farm, was billed as the first office development to officially open along Allen’s Highway 121 corridor, and its October 2024 grand opening drew more than 300 people. That kind of turnout underscores why city leaders see the highway as more than a line on a map: it is already a place where office users, developers and public investment are converging.

McKinney’s side of the corridor has its own anchor in District 121. The eight-story Class A office building was completed in 2023 as part of a $250 million mixed-use project on 17.5 acres next to Craig Ranch at the northeast corner of State Highway 121 and Alma Road. The McKinney Economic Development Corporation, McKinney Chamber of Commerce and McKinney Community Development Corporation have all relocated into the Kaizen Office building there, giving the branding push a physical presence on the corridor itself.

The public side of the strategy is moving as well. On April 28, Allen City Council accepted a donation of about 9.65 acres of parkland within Sloan Corners for Bravo Park, a 30-acre park planned with walking trails, a pond, pickleball courts and dog parks. The corridor campaign also leans on quality-of-life selling points, from schools and neighborhoods to dining, entertainment and culture, while promising access without the congestion tied to larger markets.

Dan Bowman of Allen EDC and Michael Kowski of McKinney EDC framed 121 North as a business-recruitment effort that crosses city lines rather than a marketing exercise alone. For Collin County, the question is whether the corridor becomes a shared engine for office, retail and jobs, or simply a sharper label for growth that was already coming.
