    Stay Informed:


    During the September 2013 flood event, numerous sections of Lefthand Canyon Drive were either damaged or completely destroyed. In addition, Left Hand Creek was completely altered throughout the canyon. Soon after the flood, Boulder County Transportation worked diligently to create temporary "winter roads" that would allow residents and service providers access to homes and properties. 

    In the summer of 2014, the damaged sections of Lefthand Canyon Drive received temporary paving aimed at making the area safer for travel while engineering teams worked on final designs for permanent repairs. 

    In the spring of 2015, the Transportation Department partnered with Central Federal Lands (CFL - a division of the Federal Highway Administration) on the final designs and construction of Lefthand Canyon Drive and adjacent sections of Left Hand Creek.   

    The CFL/Boulder County partnership provided an opportunity to improve the design and accelerate the construction schedule. The project includes not only the reconstruction of the damaged road sections, but also better shoulders to improve safety for everyone who uses the canyon, four new bridges where the road crosses the creek and restoration of Left Hand Creek in areas adjacent to the road, which will create a vast improvement of the ecological health of the creek.
