Commute Math for Front Range Home Buyers: Real Drive Times

Drive time decides where a Front Range buyer should look before price does, because the same $650,000 buys a 25-minute commute in Centennial or a 65-minute one in Castle Rock, and the difference is about four hours a week and $14,000 a year. The Kenna Real Estate Group runs the commute math with every buyer who works in downtown Denver, the Denver Tech Center, Boulder, Colorado Springs or at DIA. This post gives the rush-hour minutes from ten cities, the rail and bus alternatives, the tolls, and what an hour a day is worth in house.

The numbers below are ranges for a weekday departure between 7:00 and 8:00 a.m. and a return between 4:30 and 6:00 p.m., dry pavement, and they come from the drive tests the Kenna Real Estate Group runs with buyers and the times buyers report back after a year in the home. Drive it yourself at the real hour before you offer. Then start the search on every home for sale in Colorado with the cities that pass.

Longmont50 to 75 min60 to 90 min25 to 40 min105 to 135 min50 to 70 min

Three patterns fall out of the table. The Tech Center is the easiest office to serve from the south metro: Centennial, Highlands Ranch, Lone Tree and Parker all reach it in under 45 minutes. Boulder is served from the northwest only: Broomfield, Longmont, Arvada, Louisville, Lafayette and Erie; a Boulder office and a Castle Rock home is a two-hour day. Colorado Springs is a Castle Rock, Monument or Larkspur commute and nothing else; from anywhere north of C-470 it is over an hour each way.

Why the same distance takes twice as long

Front Range commutes stack up at a handful of known points, and the city you pick decides which ones you hit.

  • I-25 through the Tech Center and downtown. The stretch from C-470 to Santa Fe Drive runs slow both directions from 6:30 a.m. and again from 3:30 p.m.
  • I-70 through the Mousetrap. The I-25 and I-70 interchange slows Arvada, Wheat Ridge and Lakewood buyers headed east and Thornton and Commerce City buyers headed west.
  • US-36 to Boulder. Broomfield to Boulder runs freely in the express lane and crawls in the general lanes on weekday mornings.
  • C-470 at Santa Fe and Wadsworth. The south-metro east-west route backs up at every interchange from Highlands Ranch to Ken Caryl.
  • Parker Road and Arapahoe Road. The arterials that feed Parker and southeast Aurora onto I-225 and I-25 add 10 to 20 minutes before the highway starts.

Winter adds more. A snow morning on I-25 doubles the Castle Rock time, and the Palmer Divide between Castle Rock and Monument closes I-25 several times each winter. Buyers commuting to Colorado Springs from Douglas County need a plan for those days. See why the car is what trips people up when they move to Colorado.

RTD rail: which line serves which suburb

RTD's rail network turns a highway commute into a fixed number of minutes, and the Kenna Real Estate Group maps every buyer's shortlist against the stations.

  • A Line. Union Station to DIA in 37 minutes, with stations serving Central Park, Peoria in Aurora, Gateway and 61st and Peña. Buyers working at the airport or downtown pick homes within 10 minutes of these stations.
  • E Line. Union Station south through the Tech Center to Lincoln and RidgeGate in Lone Tree. It serves Englewood, Greenwood Village, Centennial and Lone Tree, and it is the line for the DTC office. Read the executive commute on light rail from Lone Tree.
  • G Line. Union Station northwest through Arvada to Wheat Ridge at Ward Road. Olde Town Arvada is the station buyers ask for by name.
  • N Line. Union Station north through Commerce City and Northglenn to Eastlake and 124th in Thornton.
  • W Line. Union Station west through Lakewood to the Jefferson County Government Center in Golden.
  • R Line. Aurora's north-south line from Peoria through the Anschutz Medical Campus and Aurora city center to Lincoln, connecting to the E Line at the Tech Center.

A home within a 10-minute walk or a 5-minute drive to a park-and-ride turns a 50-minute drive into a 40-minute ride with a laptop open. Homes in that circle sell for more and sell faster.

Bustang: the Fort Collins and Colorado Springs commute without driving

Bustang is the Colorado Department of Transportation's interregional coach service. The North Line runs Fort Collins and Loveland to Union Station on a weekday commuter schedule, and the South Line runs Colorado Springs and Monument to Denver, with Wi-Fi, outlets and a restroom on board. A buyer with a downtown Denver job and a Fort Collins or Colorado Springs budget uses it two or three days a week and works on the bus. Check the schedule against your office hours; the last evening departures are early for anyone who works past 6 p.m.

Tolls: E-470, the Northwest Parkway and the express lanes

The fast routes on the Front Range are paid routes, and the toll belongs in the commute math.

  • E-470. The eastern beltway from I-25 in Lone Tree around DIA to I-25 near Thornton. Parker, Aurora and Brighton buyers use it to reach the airport and the north metro. It is cashless; an ExpressToll account pays the lowest rate and license-plate billing pays the highest.
  • Northwest Parkway. The continuation from I-25 in Thornton to US-36 in Broomfield. It links the north metro to Boulder without touching I-25 through downtown.
  • Express lanes. I-25 north of Denver toward Johnstown, I-25 south from C-470 toward Castle Rock, US-36 to Boulder, C-470 across the south metro, and I-70 in the mountains. Prices change with traffic, and a daily user pays a real monthly number.

Price your route on the ExpressToll and E-470 rate pages for the exact entry and exit points, then multiply by 20 workdays. A buyer who plans to use E-470 both ways to DIA every day should add that monthly figure to the mortgage payment before comparing Parker to Aurora.

What an hour a day costs in dollars

Use two numbers: miles and hours. The IRS standard mileage rate for 2025 was 70 cents per mile, which covers fuel, tires, maintenance and depreciation. A commute of 20 miles each way is 40 miles a day, or $28 a day, $140 a week, and $7,000 a year over 250 workdays. Then value the time. An hour a day round trip at $30 an hour is $7,500 a year. Together an extra hour a day on a 40-mile round trip costs about $14,500 a year, before tolls and before the second car a two-commute household needs.

Turn that into house. At a 6.5 percent rate, $1,200 a month of principal and interest supports about $190,000 of loan. A buyer who moves the search 25 minutes closer to the office and keeps the same total monthly outlay can raise the purchase budget by that amount, or keep the budget and bank the difference. Mike Oswald, VP of Mortgage Lending at Rate, NMLS 261003, Equal Housing Lender, runs both versions of that payment for Kenna Real Estate Group buyers; you are free to use any lender. The Colorado home financing guide lists the loan options.

Hybrid schedules change the answer

Two days a week in the office changes the math by more than half, and it is why Castle Rock, Erie, Brighton and Longmont sell to buyers with downtown employers. A 60-minute commute twice a week is four hours; five days is ten. The Kenna Real Estate Group asks every buyer three questions: how many office days a week, whether that number is written into the job or a manager's preference, and whether the office itself is moving. A buyer whose company is leaving downtown for the Tech Center in 18 months should shop the E Line, not the A Line. For remote workers, the office is the spare bedroom, and work-from-home living in Denver covers what that home needs.

Two jobs, two offices

A household with one job in Boulder and one in the Tech Center has one answer: the middle. Arvada, Westminster and west Denver put both commutes in the 30-to-50-minute band. Downtown plus DIA points at Central Park, Lowry and central Aurora on the A Line. Downtown plus Colorado Springs points at Castle Rock, with one partner on Bustang. The Kenna Real Estate Group plots both offices on the map first and draws the search area from there, which is the opposite of starting with a favorite neighborhood.

How to test the commute before you offer

  1. Drive the route from the actual address at 7:30 a.m. on a Tuesday, Wednesday or Thursday, and again at 5:15 p.m.
  2. Run the same trip on the RTD trip planner and note the station and the walk from the house.
  3. Price the tolls on the ExpressToll rate page and multiply by 20.
  4. Ask the seller, in the disclosure questions, how long their own commute took and where.
  5. Check the city's planning page for road projects on the route; a two-year interchange rebuild is two years of your commute.

Buyers relocating from out of state get the full version of this test in the Colorado relocation services program, and the Highlands Ranch commute breakdown shows the numbers for one suburb in detail. Start the neighborhood search on Explore Centennial, Explore Parker, Explore Arvada or Explore Broomfield, and read how we help buyers for the rest of the process.

How long is the train from Union Station to DIA?

The RTD A Line runs Union Station to DIA in 37 minutes, with stops at Central Park, Peoria and Gateway that serve Denver and Aurora neighborhoods along I-70.

Can I commute from Castle Rock to Colorado Springs?

Yes, 40 to 60 minutes at rush hour on dry roads. Plan for the Palmer Divide, which closes I-25 between Castle Rock and Monument several times each winter.

Which Front Range cities work for a Boulder job?

Broomfield (20 to 35 minutes), Longmont (25 to 40), Louisville, Lafayette, Erie and Arvada (30 to 50). From the south metro, Boulder is 60 to 105 minutes each way.

What is Bustang?

CDOT's interregional coach service with Wi-Fi and outlets. The North Line runs Fort Collins and Loveland to Union Station and the South Line runs Colorado Springs and Monument to Denver on weekday commuter schedules.

How much does a 40-mile round-trip commute cost per year?

About $7,000 in vehicle cost at the 2025 IRS rate of 70 cents per mile over 250 workdays, plus about $7,500 if you value an hour a day at $30. Tolls and a second car come on top.

How much more house does a shorter commute pay for?

At a 6.5 percent rate, the roughly $1,200 a month saved by cutting an hour a day and 40 miles supports about $190,000 more loan, or the same home with $1,200 a month left over.

Does living near an RTD station raise a home's value in the Denver metro?

Homes within a 10-minute walk or 5-minute drive of a park-and-ride sell faster and for more than the same home 20 minutes from a station, and they hold demand from buyers with downtown, DTC and DIA jobs.
