Estrada de manutenção da Ecovias, Maintenance road in São Bernardo do Campo and São Vicente, Brazil

The Ecovias maintenance road runs parallel to the Imigrantes and Anchieta highways while passing through the Serra do Mar State Park. It was built to support the operation and upkeep of these major transportation corridors.

A tile monument at Rancho da Pamonha claims the road was the Trilha do Perequê in 1528, a branch of the Peabiru used by the Portuguese to climb from the coast to the plateau. Father Anchieta later used it to trace his path to Piratininga. DERSA reused the route in 1922 as access for building the new Anchieta highway, hence the name maintenance road. From 1970 it served the construction of the Imigrantes ascent, and in 1976 the Imigrantes opened.

Locals call it "Manú", a nickname for the maintenance road. A tile monument at Rancho da Pamonha claims the route was already the Trilha do Perequê in 1528, used by the Portuguese to climb from the coast to the plateau as a branch of the Peabiru network. The road is often confused with the Estrada Velha de Santos, which lies much further north.

Most of the road is closed to vehicles; only the stretches turned into emergency routes are used, by Ecovias service cars, Highway Police vehicles and some private cars. The main trunk is about 21 km long, with ramps climbing more than 10 m every 100 m, and only six metal bridges cross the terrain. The route lies inside the Serra do Mar State Park, which suffers degradation and pollution from sacrifice rituals held there.

The road was built in the early 1970s to reach the work fronts of the Imigrantes Highway's uphill carriageway. Its original project foresaw 34 metal bridges, but 28 were dropped during construction; only six were built, so the route follows the Serra do Mar relief with ramps climbing more than 10 metres every 100 metres.
