An in-ground channel for linear lighting is disclosed. In the channel, two upright sidewalls are spaced apart by a bottom. Each of the sidewalls has an inwardly-extending upper support flange proximate to an upper end. The inwardly-extending upper support flanges are aligned with one another on respective sidewalls. A shelf is mounted between the two upright sidewalls at a position below the inwardly-extending support flanges. The shelf divides the in-ground channel into an upper section and a lower section. The upper section houses linear lighting and the lower section provides a raceway. The channel has only a single mounting flange attached to one of the two sidewalls at a position level with the bottom. The channel typically also includes a cover adapted to engage the upper support flanges. The shelf may be removable, mounted via a pair of inwardly-extending lower support flanges, for access to the lower section.
