Interstate 80 is both the Alan S. Hart Freeway and Purple Heart Trail in California. A pair of small guide signs proclaim the designations as the freeway enters Sierra County from Verdi, Nevada. Hart was a former Caltrans district head and worked for the department for over 40 years. His resume includes the overseeing of both the construction of Interstate 280 in San Francisco and Interstate 80 from Sacramento to the Nevada state line. The Purple Heart Trail designation was applied to parts of Interstate 80 between Interstate 5 and the state line in 2001. Photos taken 09/09/05.
Interstate 80 travels parallel to the Truckee River between the state line and Donner Lake. The four-lane freeway includes a jersey barrier median. Note the "bridges may be icy" sign referencing all of the over and underpasses along Interstate 80 between Verdi and Crystal Lake, a distance of 40 miles. This style of sign was borrowed from NDOT standards, where the sign references all of the bridges along a set number of miles. The narrow nature of the valley essentially curtails any notion of freeway widening. Photos taken 09/09/05.
The first interchange along Interstate 80 within the Golden State serves the isolated area of Farad at Exit 201. Farad constitutes a small settlement along the Truckee River accessible only by the freeway. Photo taken 09/09/05.
A compact partial-cloverleaf interchange joins Mystic Road with Interstate 80 at Farad. The Exit 201 off-ramp essentially represents a right-hand turn lane from Interstate 80 west. Mystic Road spurs east to the Truckee River. Photo taken 09/09/05.
The beauty of the Sierra Nevada continues to set the tone along Interstate 80 westbound beyond the Farad interchange. Photos taken 09/09/05.
Interstate 80 travels north-south between Verdi, Nevada and Iceland. The freeway approaches Floriston (Exit 199) ahead of the western turn toward Truckee. Meeting the freeway at Exit 199 is Floriston Way, a short connector between the freeway and Floriston itself. Photo taken 09/09/05.
The concrete freeway, recently repaved in 2004-05, of Interstate 80 meandering along the Truckee River toward Floriston. The surface here is in much better shape than the rutted large-aggregate concrete at and beyond Donner Pass. Photos taken 09/09/05.
Westbound Interstate 80/Alan S. Hart Freeway reaches Exit 199 Floriston Way (partial-cloverleaf interchange). Photo taken 09/09/05.
The California-standard angular shield debuts as Interstate 80's first westbound reassurance shield near Floriston; many of these t through the mountains are neutered (without a state name within the route marker). These types of signs are found throughout the freeway between the California-Nevada State Line and Sacramento. Photo taken 09/09/05.
Interstate 80 mileage sign featuring the next destinations of significance, Truckee, Auburn, and Sacramento. The freeway travels through sparsely populated areas from Donner Pass westward toward Auburn and the Central Valley. Photo taken 09/09/05.
Interstate 80 rounds the bend between Iceland and Hinton alongside both the Truckee River and Union Pacific Railroad. Photos taken 09/09/05.
Nearing the folded-diamond interchange (Exit 194) with Hirschdale Road along Interstate 80 westbound. Hirschdale Road flows south 1.3 miles from Exit 194 to Hirschdale. Photo taken 09/09/05.
Travel north from Interstate 80 toward the Tahoe National Forest Boca and Stampede Recreation Areas. Stampede Meadow Road travels northwest from Exit 194 to Boca Road alongside the Boca Reservoir. Boca Road heads west to Old Reno and Prosser Dam Roads. Stampede Meadow Road heads north along the east side of Boca Reservoir to Stampede Reservoir in Sierra County. Photo taken 09/09/05.
Interstate 80 passes over both the Union Pacific Railroad line and Truckee River ahead of the Exit 194 ramp departure to Hirschdale Road south and Boca Road north. Glenshire Drive extends west from Hirschdale Road nearby to the community of Glenshire and California 267 at Truckee. Parts of Glenshire Drive follow the original alignment of U.S. 40. Photo taken 09/09/05.
A truck weigh station lies along the stretch between Hirschdale Road (Exit 194) and Prosser Village Road (Exit 190). Interstate 80 passes by nearby Glenshire at an elevation of 5,680 feet above sea level. Photos taken 09/09/05.
Westbound at the Exit 190 diamond interchange with Prosser Village Road. Prosser Village Road links Interstate 80 with Prosser Dam Road and Prosser Creek Reservoir to the north and Glenshire Drive via Highland Avenue to the south. Photo taken 09/09/05.
Approaching the town of Truckee and junction California 89 & 267 (Exit 188) on Interstate 80 westbound. California 267 constitutes the Truckee Bypass between Interstate 80 & California 89 and Brockway Road east of town. The state highway joins Truckee with Kings Beach and Lake Tahoe (junction California 28 (North Lake Boulevard). Photo taken 09/09/05.
A pair of small guide signs remind motorists of the Exit 188 connections to Lake Tahoe (via California 267 south) and Sierraville (via California 89 north). Lake Tahoe is a 12-mile drive to the south. Sierraville resides 23 miles to the north at the California 89 junction with California 49. Photo taken 09/09/05.
Nearing the Exit 188 diamond interchange with California 89 north and California 267 (Glen Carlson Memorial Bypass) south. California 28 (North Lake Boulevard) encircles Lake Tahoe from between U.S. 50 (via Nevada 28) and Nevada 89 at Tahoe City. Photo taken 09/09/05.
Exit 188 (Junction California 89 north and California 267 south) departs Interstate 80 westbound at the Truckee Bypass. The Truckee Bypass replaced the California 267 routing along Donner Pass Road and Brockway Road to the west. The diamond interchange with Donner Pass Road was partially removed due to the construction of the interchange with the newer Truckee Bypass. A half-diamond interchange still serves Donner Pass Road from Interstate 80 east. California 89 southbound merges onto Interstate 80 between Exits 188 and 185. Photo taken 09/09/05.
The next exit along Interstate 80/Alan S. Hart Freeway west is Exit 186, Donner Pass Road (former California 267 and former Business Loop I-80) passes through downtown Truckee and emerges near High and River Streets at Interstate 80 & California 89. Signed simply as Central Truckee, Exit 186 joins Donner Pass Road with the freeway via a partial-diamond interchange. Donner Pass Road represents the original U.S. 40 alignment through Truckee. Photo taken 09/09/05.
An angular Interstate 80 west reassurance shield is posted after the Exit 188 on-ramp from Donner Pass Road at Truckee. This style of shield, which is more angular than older shields, has become more prominent on California's freeways. While it is not the best-looking shield, at least it retains the state name. Photo taken by Jeff Royston, 01/00.
One half mile west from the California 89 southbound departure from Interstate 80 westbound at Exit 185. California 89 travels south along the Truckee River to junction California 28 at Tahoe City, a distance of 14 miles. Photo taken 09/09/05.
Interstate 80 westbound at the split with California 89 south (Exit 185). California 89 meets U.S. 50 at South Lake Tahoe in 41 miles. The state highway follows West Lake Boulevard south along the lake between Tahoe City, Meeks Bay, and South Lake Tahoe. California 89 follows U.S. 50 west briefly before continuing south to its end at California 88, 57 miles south of Truckee. Photo taken 09/09/05.
Donner Pass Road (Historic U.S. 40) crosses paths with Interstate 80 again at Exit 184. The parallel roadway leaves Truckee and skims the shore of Donner Lake en route to Donner Pass. Photo taken 09/09/05.
Before Interstate 80 passes Donner Lake, a California Agricultural Inspection Station awaits. The facility requires all vehicles to stop for inspection of any agriculture brought from out of state. This facility was relocated and remodeled; we'll have to return here to get new pictures. Note that commercial trucks and vehicles carrying livestock must still stop. Photo taken 09/09/05.
Entering the former California Agricultural Inspection Station booths along Interstate 80 westbound, the inspection procedure normally takes a short amount of time, and when inspectors are not on the scene, vehicles may proceed through at a much reduced speed (normally about 5 mph). Photo taken 09/09/05.
A button copy overhead remains in use at the U.S. 40/Donner Pass Road (Exit 184) off-ramp of Interstate 80 west. Donner Pass Road passes over the freeway between west Truckee and Donner Memorial State Park. The road is signed with brown Historic U.S. 40 signs. Travelers taking the road west from Donner Lake have a steep climb toward Donner Pass itself. A concrete arch bridge dating from 1925 still carries motorists over a ravine at McGlashen Point. This interchange would serve as the west end of the business loop if it were still routed through Truckee (now it is decommissioned). Photo taken 09/09/05.
The rutted concrete begins along Interstate 80 westbound on the drive toward Donner Pass. The concrete is notoriously bad through this stretch of the High Sierra due to heavy truck traffic and age. Pictured here is an older mileage sign listing the distance to Auburn and Sacramento. Photo taken 09/09/05.
Beginning the climb toward Donner Summit along Interstate 80 westbound. The freeway sees a vista point between the Donner Pass Road (Historic U.S. 40) interchange and Donner Lake Exit. The view area allows motorists to enjoy the scenery of nearby Donner Lake. Photos taken 09/09/05.

Castle Peak rises to a height of 9,103 feet in the distance as Interstate 80 climbs toward Donner Pass (elevation 7,239 feet above sea level). The Donner Pass Rest Area lies at the summit itself. Don't travel through this area during the winter without your snow chains handy as Donner Summit averages 54 inches of precipitation per year. The pass itself derives its name from the Donner family tragedy of November 1, 1846. Five feet of snow fell on the party of 87 and only 47 pioneers survived the 30 to 40-foot drifts. Photos taken 09/09/05.
