[7] Beginning in 2015, the state began a major re-evaluation of the GLX project due to significantly increased costs.

In May 2016, the state indicated that the Community Path would only be built as far as Washington Street in the revised plan to avoid a costly bridge.

In some sections, the path would be lowered to track level to eliminate costly retaining walls, resulting in fewer connections to cross streets than previously planned.

Cycling advocates have raised concerns about safety of the narrowed path given the expected levels of bicycle traffic.

[17] A separate project constructing Reavis Field for Somerville High School moved a small section of the path onto a protected on-street detour until October 18, 2023.
