DENVER (KDVR) — A piece of history was brought to light as Denver Water crews replaced water lines under East Colfax Avenue.
Denver Water said crews are replacing pipelines along a 5-mile stretch under Colfax Avenue before building new bus routes for the new Bus Rapid Transit system, scheduled to open in 2027.

Since the project began in June 2023, crews have replaced underground cast iron pipes dating to the late 19th century.
“The Colfax pipeline has proven itself for more than 100 years, but these improvements are necessary to ensure a reliable water supply for the next century,” said Katie Ross, technical project manager for Denver Water.

While digging trenches on the street, crews uncovered trolley tracks that were part of the city’s old streetcar system that operated in the 20th century.

That streetcar was abandoned in the 1950s and Denver Water said the tracks were paved so cars and buses could take over the roadway.
The old tracks are made of steel, so workers used a diamond saw blade and an excavator to make room for pipe replacement.
