C-470/Alameda Interchange
Submitted by SEMA Construction

In an effort by Jefferson County and the city of Lakewood to provide regional access to the historic Rooney Ranch district, while limiting the effects of increased traffic along the hogback and Dinosaur Ridge, the regional transportation facilities at C-470 and Alameda were updated. The planning for the interchange began in 1990 with the goal that the interchange would be ready to move forward when development began in the Rooney Valley. The bridge was widened from two to five lanes with multiple-lane ramps. Design of the entry monuments and bridge included landscaping, stone bridge elements, ornamental fencing and lighting, along with an enhanced design of the retaining walls.
