		In the distant background is the Wellington Road interchange (#186), the main entrance into the southcentral part of London from Highway 401.
		The lanes at left are in the centre of the highway and are the express lanes.
		Since interchanges are largely only accessable from the collector lanes, special "transfers" every few kilometres allow vehicles to switch between the express and collectors.

	FindLaw for Legal Professionals - Case Law, Federal and State Resources, Forms, and Code
		Because a DCE may not be used for a highway interchange construction project, and Stage 2 was insufficiently defined, the existing DCE could not be used to satisfy FHWA's NEPA obligations.
		West filed a complaint in district court seeking, in part, a declaration that the interchange is not categorically excluded from NEPA and an injunction requiring work to cease on the project until the agencies prepared an Environmental Impact Statement.
		It is axiomatic that a new, fully- directional interchange cannot simultaneously relieve traffic congestion and yet have no significant impact on travel patterns.10 The interchange construction project, therefore, fails the first prong of the test for a DCE -- satisfying the general CE criteria -- and is inconsistent with the terms used in the regulation.

	Parclo interchange - Wikipedia, the free encyclopedia
		The parclo interchange was developed by the Ontario Ministry of Transportation [1] as a replacement for the cloverleaf on 400-Series Highways, removing the dangerous weaving patterns and allowing for more acceleration and deceleration space on the freeway.
		In addition, the Solomon Pond Road interchange on I-290 in Northborough, Massachusetts was converted from a B2 interchange to a B4 interchange in the mid-1990s with the construction of the Solomon Pond Mall.
		In the United States, folded diamonds are frequently used in interchanges with roads that have a railroad line closely paralleling the surface street; entrance/exit ramps are not permitted to have level crossings in modern American practice.

	Kurumi's Field Guide to Interchanges - Glossary
		An interchange between two freeways where access is provided by an auxiliary divided road, connected to each freeway with a trumpet interchange.
		In our context (interchange diagrams), a freeway is a road with full access control in the interchange area: the reason an interchange is used instead of an at-grade, signalized intersection.
		An interchange with one or more loop ramps, but fewer than the eight ramps needed to form a full cloverleaf.

	Ronald Regan Cross County Highway (Site not responding. Last check: 2007-11-03)
		The highway was originally conceived in the 1940's as a short three mile lateral between the Millcreek (I-75) and Northeast (I-71) expressways to provide access primarily to the Blue Ash Airport, which was expected to become the region's major airport.
		Two of the interchanges are not fully grade separated, with one of the I-71 interchange ramps forming a 3-way intersection with the through lanes of Cross County Highway.
		Unlike the crude eastern portion of the highway, the new western section was built to full interstate standards, with a wide grass median and high speed interchanges.

	King's Highway 410 - Images
		Highway 410 has come a long way from the super-2 type of expressway that it was when constructed in the early 1980s.
		Highway 410 is now 6 to 8 lanes for its entire length and has several multi-level freeway to freeway interchanges.
		The Highway 407 interchange was located in close proximity to the Derry Road interchange, because of this the Derry Road interchange was reconfigured with braided ramps on the north side to eliminate the possibility of weaving.

	Jeff's Streets Page--SF Bay Area - Highway 17
		The two loop ramps from Highway 17 onto Highway 9/Saratoga Avenue would be demolished, and the remaining two ramps from Highway 17 onto Highway 9 would now meet Highway 9 at two separate signalized intersections on opposite sides of the overpass.
		A similar congestion situation to Highway 17 south of Highway 85 occurred on Highway 17 between Highway 85 and Camden Avenue right after Highway 85 was opened in 1995, and Caltrans eventually extended the third lane (on both sides of the freeway) down from Camden to Highway 85, eliminating that bottleneck instantly.
		This ramp was originally proposed to be part of the interchange, which was first proposed to have no circular loop ramps, and you can even see part of the concrete abutment for the proposed ramp on your left alongside the short upgrade on the northbound ramp leading to the existing loop ramp.

	Building an effective highway interchange system - SC3000.COM
		Interchange systems enable motorists to merge onto orthogonal highway routes, with little or no disruption to the flow of traffic.
		For some, this approach creates an ugly depression and bump along the two divergent highways, but it also requires a mixture of road-to-highway and highway-to-highway ramps to be 100% effective; and it is not designed for terminating highways.
		The effect of the interchange system being developed here was tested by restricting all residential zones at the north end of H1 and all industrial/commercial zones at the south end of H1, thus making the H1-S route critical to city development.

	Pennsylvania Highways: Pennsylvania Turnpike
		The Middlesex Interchange was upgraded with a new toll plaza and ramps, and renamed the Carlisle Interchange.
		The Gateway Interchange had three more lanes added to bring its total to 11, the Pittsburgh Interchange's increased to 10 lanes, and a new Harrisburg East plaza was built to provide direct access to Interstate 283 and PA 283.
		Unfortunately, inflation caught up with the highway and on September 1, 1969, the PTC raised the passenger-car rate from 1 cent/mile to 1.9 cents/mile which was the first increase in 29 years of operation.

	Schedule / Stages
		The proposed construction is broken into three subparts for the significant interchanges at Highway 100 (Stage 3A), Interstate 35W (Stage 3B) and Highway 77 (Stage 3C).
		Construct up to 6 travel lanes in each direction, construct a Semi-directional interchange (where the majority of left turns are provided by direct connections using multiple-level structures to accommodate high traffic volumes at higher speeds) at Highway 100, construct a collector-distributor roadway system through the Highway 100 interchange and replace numerous bridges.
		Single-point interchanges (at-grade signalized intersections on the minor roads designed to allow high volumes of left turns from the off-ramp to flow at higher speeds with minimum delays, allowing right turns to flow independent of the signal) will be provided at Penn Ave.

	SitNews - Glenn-Parks Highway Interchange Dedicated (Site not responding. Last check: 2007-11-03)
		Wasilla, Alaska - The new Glenn Highway and Parks Highway interchange is a significant improvement in Southcentral Alaska's transportation system that will be a boon to Alaska motorists, Governor Frank Murkowski said at ceremony dedicating the interchange on Friday.
		The new interchange was designed to accommodate the vast numbers of travelers who shift between the Glenn Highway and the Parks Highway while traveling along Alaska's main north-south transportation corridor.
		As the interchange occurs in an area of considerable wetlands and important salmon habitat, designers worked hard to protect and in some cases enhance the natural environment, the governor said.

		The DOT and the Federal Highway Administration did computer simulations that found the proposed change would result in an average speed of 45 miles per hour for drivers in rush hour, compared to speeds of less than 15 mph under the current setup.
		The Federal Highway Administration approved construction of the interchange, including the lane configuration on I-295, after the DOT submitted a report in January 1994 that included predictions of future traffic.
		For the section of I-295 between the interchange and St. Augustine Road, the report predicted that 69,000 to 89,000 vehicles a day would be on the highway in 2000.

	An Initial Assessment of Freight Bottlenecks on Highways - 5.0 - FHWA (Site not responding. Last check: 2007-11-03)
		The delay estimation methodology calculated delay resulting from queuing on the critically congested roadway of the interchange (as identified by the scan) and the immediately adjacent highway sections.
		This means that truck hours of delay were calculated on only one of the two intersecting highways or two of the four legs on a interchange, potentially underreporting total delay at the interchange.
		Because the underlying Highway Performance Monitoring System data do not detail traffic counts by time of day, the actual number of trucks exposed to peak-period congestion is unknown, and therefore the reported truck hours of delay shown here provide good index to the relative impacts of the bottlenecks, but are not reliable absolute numbers.

	TIME.com: The Overlooked Cloverleaf -- Aug. 23, 1971 -- Page 1
		Residents of Manchester, Conn., were startled six years ago when they learned that a highway interchange proposed for Interstate 84 would munch up 50 acres of greenery that had been zoned for recreation near the center of town.
		The interchange would be built in the town as planned, but Manchester would still be able to keep its recreational facilities.
		Under the compromise plan, the interchange was designed so that Manchester's existing recreational facilities could be preserved within the "cloverleaf"—the network of curving ramps that connects the intersecting highways.

	Kurumi's Field Guide to Interchanges
		An interchange is a grade-separated intersection (one road passes over another) with ramps to connect them, as pictured.
		However, many interchanges are slight variations of a few basic types, that adapt well to various situations and have been proven over the decades.

	Highway Plan Threatens Stones River Battlefield
		From what she knows about the proposal, from media accounts and second-hand information, the proposed interchange site is part of the core battlefield that was identified in the parks general management plan as an area that needs protection.
		He said the interchange is controversial in the community and the justification of the proposed interchange is unclear to the public.
		According to press reports, city officials argue that the interchange and road widening are necessary to ease traffic congestion in Murfreesboro, a city that has grown 30 percent between 1990 and 1998.
