The Denver - Boulder Turnpike (US 36) turns 60 today. It was the first limited-access highway in the state of Colorado when it opened on January 19th, 1952 and also one of the first freeway-type roads in the Rocky Mountains. It was originally a toll road, but became toll-free after the bonds were paid off in 1967, much earlier than originally anticipated. The turnpike remains and important road today.

I took that, it was a late Sunday afternoon. At rush hour it gets fairly busy, before there were 5 traffic lights to get from 121 WB to DNT south...

Another toll facility is coming to the Tidewater region. The US 17 bridge across the Intracoastal Waterway in Chesapeake will be replaced by a new, higher toll bridge with 4 lanes. The current bridge opens approximately 6,000 times a year for shipping. It will still be possible to cross the waterway toll free, via alternate routes such as I-64 and Battlefield Boulevard. The replacement will cost $ 412 million.

The new Indian River Inlet Bridge in southern Delaware opened to traffic today. The new cable-stayed span in Highway 1 replaces an older drawbridge north of Bethany Beach.

Oh, NICE! I feel like they've been working on those bridges since I was a kid.

It's also the second cable-stayed bridge on Route 1 now...

Florida's Turnpike turns 55 today. On January 25th, 1957, the first 110 miles of the toll road opened between Miami and Fort Pierce. The entire toll road was completed just 7 years later. It was the first long-distance limited access highway in Florida.

The US 68 Eggner Ferry Bridge in southeastern Kentucky has collapsed due to a barge colliding with it on Lake Kentucky. No injuries or fatalities have been reported, and no cars are in the water.

Here's a pre-collission photo:

What major city (with a metro population of over 3 million people) has the most efficient surface streets? Which city has the least efficient?

By efficiency i'm focusing mainly on travel times. If i live 20 miles from downtown and can only take surface streets to get there, what cities will have the quickest drive into downtown and which cities will have the slowest?

Least efficient is probably New York.

Most efficient? Probably Detroit.

I am in agreement that Detroit has very efficient arterial roads. This video really illustrates the point of how you can quickly get from point A to point B when driving Detroit arterial roads (largely thanks to Michigan Left turns).



This video was taken during the PM rush and averaged over 50 mph in both directions (over a 10 mile stretch). I know a wide 6-lane boulevard with high speed limits cutting through the city is the last thing someone who envisions a walkable community wants. However, as long as urban sprawl exists roads like this are a necessity.

The lack of local traffic in the Detroit city proper also plays a role I think. The road network was designed for a much larger population. Through traffic from the suburbs will mainly use the freeway system.

To be fair, Detroit has rather large AADT on its arterial system:

Detroit Area:
87,300: M-59 between Van Dyke to Garfield (8-lane boulevard w/Michigan Left turns)
72,300: Telegraph between I-696 & 13 Mile (8-lane boulevard w/Michigan Left turns)
68,800: M-5 Between 13 Mile & Maple (8-lane boulevard w/Michigan Left turns)
68,800: Van Dyke between 16 Mile & 18 Mile (6-lane boulevard w/Michigan Left turns)
65,500: Woodward Ave between 13 Mile & Maple (8-lane boulevard w/Michigan Left turns)
64,000: 8 Mile Road between The Lodge & I-75 (8-lane boulevard w/Michigan Left turns)
54,000: Big Beaver Road between Livernois & John R (6-lane boulevard w/Michigan Left turns)
53,000: Rochester Road between Big Beaver & Long Lake (6-lane boulevard w/Michigan Left turns)

It appears that the ship at the US 68 bridge in Kentucky was traveling in the wrong canal. It took down one span.

The news article on that bridge is incorrect anyway. It's in South Western Kentucky. It was slated to be replaced and I guess this gives KYTC a reason to speed things up.

There's a few somewhat unnecessary Michigan Lefts on the also somewhat unnecessary highway section of PA Route 272 outside of Lancaster.

I wish my metro had utilized Michigan Lefts along with signal spacing. Here in Florida they have a need to add a signal for every little complex or shopping center. We have lengthy traffic signals, I know of one that can be as long as 8 minutes long at times, I know quite a few during rush hour are 5 minutes long. It's frustrating, you actually won't make it to the next light if you do the speed limit sometimes, you have to speed or you will sit another 5 minutes. Sometimes it doesn't matter, you get stuck regardless.

I found this video that you posted on youtube and it's a great example of what you're describing. You get the start of green at Sunset Point Road (50 seconds into the video) just to come to a lengthy red light at 10th street (1min 25sec - 2min):


I-275westcoastfl, do you know how fast this video was sped up? I was curious how long the cycle length the light at 10th street was running.

I use these roads everyday. I find Michigan left turns to be more of a gimmick than anything else. They're also a huge waste of physical space as all that extra land has to be acquired for the medians.
