Lock 39, built between 1831 and 1836, is located in the municipality of Cubillas de Santa Marta (Valladolid), at kilometer 119.700 of the Southern Branch of the Canal de Castilla. This structure forms part of the final phase of the canal’s construction and addresses the need to regulate the water level, ensure navigation, and divert water to auxiliary infrastructure along a section of great territorial importance. Its overall function was to guarantee the continuity of the hydraulic route and allow for the controlled use of the water drop.
Several elements associated with the lock complete its functional understanding. The main bridge over the lock stands out, with its segmental arch and limestone masonry. It spans the lock basin and allows passage of the N-620 road towards Valoria la Buena, with its parapets and flared wing walls in good condition. Two smaller bridges also serve the diversion channel, one aligned with the lock bridge and the other at the outlet of the spillway. Constructed of brick and masonry, they ensure the continuity of the road over the dam. The complex is completed by the lock keeper’s house, a single-story rectangular building with a stone base, brick walls, a wooden frame, and a curved ceramic tile roof. Currently unused, it is well-preserved and protected for its structural value.
Access is from kilometer point 100.200 of the N-620 road, taking the turnoff towards Valoria la Buena, which passes over the lock bridge, 200 meters from the N-620
