I-25 bridge lanes mismatched for now

QUESTION: On I-25 there is a bridge in the new construction between Fillmore and Garden of the Gods Road. Why is the southbound lane at least 10 feet wider than the northbound lanes? It is the bridge over Ellston Street. The way it is now, there will be no room for a shoulder on the northbound side, and this is asking for many accidents.

ANSWER: When Colorado Department of Transportation started the COSMIX project, it had to move the two lanes of traffic onto one bridge, requiring that the southbound side be wider to accommodate the traffic shifts in the detour area, according to CDOT’s Bob Wilson. For now it will stay as it is because eventually lanes will be added and both sides will get wider.
