Driving Directions from Denver International Airport

Upon leaving the terminal or the rental car area, look for signs marked "Airport Exit" and "To I-70 & I-225 via Peña Blvd." It is not necessary to take the E-470 Tollway to or from I-70, since it doesn't save time and costs extra.) Stay on Peña Blvd until it merges with I-70 westbound.

Stay in the left or center lanes to avoid exiting onto I-225 and other cross streets, and continue westbound on I-70 for about 4 miles. Watch for the I-270 exit on the right, labeled "Westminster/Ft. Collins," that comes at about 14 miles from DIA. It is also labeled Exit 279, "US-36 Boulder."

Take I-270 past Quebec, Vasquez, and York Streets, and past I-76 at 18 miles from DIA. Stay in the left lanes, until you pass under a "US-36 West/Boulder" sign at about 20 miles from DIA. (Do not exit to the right, towards Ft. Collins or Broadway.)

Stay on US-36 into Boulder, past the Foothills Parkway/Table Mesa/South Boulder Rd exit, and take the Baseline Rd exit to the right, at about 39 miles from DIA.

Stay to the left on the exit ramp, and turn left (west) on Baseline Rd. Travel under the US-36 overpass, to the first stoplight, at 27th Way. Get in the left turn lane and follow 27th Way up the hill to Broadway.

The Boulder Labs of the Department of Commerce are straight ahead, directly across Broadway, at about 40 miles from DIA.

Visitors are required to show photo identification upon arrival and must wear a visitor badge at alltimes while on the NIST campus.
