I-90 on ramp closed for the rest of the year, additional traffic lights added to help with traffic overflow
RAPID CITY, S.D. — The I90 eastbound on-ramp located on Haines Avenue is now closed due to construction for the rest of the year.
The construction is part of a bigger project to add lanes between exits 58 and 59.
Those lanes will make it safer for drivers to exit the interstate and merge into traffic.
A detour on Haines can be accessed at the intersection on Mall Drive, where additional stop lights have been installed to help with the expected overflow of traffic.
