The new Marshall Junior High School opened in August of 2017 to serve students in grades 6-8. The project was part of the Legacy 2017 building program born out of the passage of a $109,200,000.00 bond issue approved by MISD voters in May 2015. Huckabee, Inc., served as the architect for the Legacy 2017 building program, with RLM General Contractors of Longview serving as the general contractor for Marshall Junior High. Project Manager for the Legacy 2017 building program was Lockwood, Andrews & Newnam, Inc. (LAN), of Houston, Texas. Since 1981, Marshall Junior High had been located on West Houston Street in the building formerly known as Marshall High School. Originally constructed in 1924, the building had served Marshall students in grades 7-8 since the construction of the "new" Marshall High School on Maverick Drive, which opened in 1980. The new, 186,000-square foot, state-of-the-art junior high school features a two-story academic wing; a fine arts hall to serve students in band, choir, orchestra, theatre and art; administrative offices; a full service kitchen with food preparation and staging for hot foods; cafetorium; double gymnasium; an athletic wing and locker rooms which are designated as storm shelters; athletic practice field with equipment storage; parking areas in both the front and back of the facility; and support drives for parent pickup and buses.

Areas in the new building have been named in honor of past educators and school communities who have contributed much to the history of Marshall Junior High School. The G.A. Rosborough Administrative Offices are named after Mr. Garfield Alton Rosborough, who spent 28 years as principal at Pemberton High School. The H.B. Pemberton Learning Center is named after H.B. Pemberton, an iconic Marshall educator who founded Central School in which would become later known as Pemberton High School.

The Dr. Jerry Payne Fine Arts Center is named after former Marshall ISD band director, Dr. Jerry Payne. Dr. Payne came to Marshall in 1977 and built the Big Red Pride band from a struggling band program to one of the most respected bands in the state during his 25 years in MISD. The Coach Willie Todd Athletic Complex is also named after Coach Willie Todd, who served as a coach at both Pemberton High School and Marshall High School and was a successful boys track coach at MHS for several years.

Hallways in the new MJHS are named after Mr. Ora Asa Johnson, who was the last principal at Pemberton High from 1976-1988 and then served as principal at MJHS from 1988-94. Another hallway is named in honor of Mr. Blaine Edmond, who was principal at MJHS from 1980-88 and served 39 years as an educator in Marshall. The Jimmy Wall Hallway honors Mr. Jimmy Wall, who served as principal from 1976-81 at the old Marshall Junior High eighth-grade campus at what is now Sam Houston Elementary. Mr. Wall later would become an administrator in MISD, being named Assistant Superintendent of Instruction in 1993.
