There are no plans to create a direct connection between Interstates 70 and The freeway for Interstate 70 ends rather ignobly at a Park and Ride at Baltimore, just east of the exchange with I Even in autumn and spring, snow is a frequent occurrence here. I follows U. At Colby, Interstate 70 swings south to rejoin U. From there, I and U. Louis, with a few exceptions. East of St. Louis, I and U. However, once in Maryland, Interstate 70 again closely follows U. The proposed subway line was to utilize a portion of the I right of way, with the existing six-lane freeway converted into a two-lane parkway.
Additionally the interchange Exit 94 between the I east end at MD Security Boulevard was slated for removal and replacement with an at-grade intersection. Cooks Boulevard, a Maryland State Highway Administration-maintained roadway, would overtake former I west to the four level interchange with I Route Numbering Committee on May 29, However funding for the Red Line project was ultimately withdrawn.
Some of the options include converting portions of Interstate 70 into a surface boulevard, adding various collector distributor lanes parallel to the freeway, additional lanes, or doing nothing. From there, I would take over SR , and a new connection would be constructed in the vicinity of U.
In exchange, the former route of Interstate 70 between Exits 98 and A, including the notorious interchange with I, would be replaced with a 35 mph boulevard. According to the Columbus Dispatch ,.
As the study progressed between and , various options were considered, eliminated, or adopted for further consideration. Design of the project began in A new ramp was also constructed from I east at Parsons Avenue to replace the exit at 18th Street. It opened to traffic on December 20, Junctions —. Junctions — Future. West of Denver in , only four portions of Interstate 70 were open to traffic: Fruita to SH 65 east of Grand Junction opened between and , between New Castle and Glenwood Springs , from Wolcott east to Vail and and Silver Plume east into Denver through The oldest sections of Interstate 70 in Colorado included the viaduct from Brighton Boulevard east to SH 2 Colorado Boulevard constructed from to September 12, The stretch east to Peoria Street was completed in , and from there to U.
The scenic stretch through Glenwood Canyon in Colorado is an engineering marvel, with the freeway often partitioning with I westbound traveling on elevated viaduct and I eastbound staying closer to grade level over old U. The west portal of the 8, foot long bore sits at 11, feet above sea level. The tunnel represents the highest elevation on the Interstate Highway System. I and U.
I east at Interstate in Kansas City, Missouri. The two freeways meet to the northwest of Arrowhead and Kauffman Stadiums. This realignment pushed a 4. Within the St. Louis, Illinois at the tri-level interchange where I and I part ways. The Stan Musial Veterans Memorial Bridge accommodates four overall lanes with full right-hand shoulders.
The span can be restriped for six lanes, but without shoulders. Long term proposals to reconstruct, replace or realign Interstate 70 east through the Elyria and Swansea community in Denver continued beyond the completion of the T-REX reconstruction of the Mousetrap Interchange where I and I meet at Globeville in Denver. The section of I east of Brighton Boulevard SH consists of an elevated roadway completed in Several options proposed for the freeway between Interstate 25 and Tower Road in Aurora, included: 2.
These three options would have pushed the freeway through the home of the National Western Stock Show to a point nearly one mile north of the original alignment. Under these scenarios, existing Interstate 70 would revert back to a surface street East 46th Avenue.
Preliminary estimates indicated that realigning Interstate 70 was the most cost effective option versus reconstructing the old freeway. Construction anticipated for will rebuild the ten mile stretch of I from I at Globeville to Chambers Road in Aurora. Toll lanes will be added in each direction. The expansion project added a full left-hand shoulder for use as a third, optional lane during peak travel periods.
When open to traffic, the Mountain Express Lane charges a tolls electronically through ExpressToll transponders or toll by plate. Congestion pricing is implemented to keep the toll lane moving at highway speeds, with rates adjusted upward during heavier traffic. Overpasses across I at both exits were replaced as well. Further east at the Twin Tunnels, construction from late Fall to Summer expanded both bores to accommodate three lanes. Interstate 70 is one of the few Interstate Highways that has traffic signals on its mainline.
The series of traffic signals is located on the connection between the Pennsylvania Turnpike Interstate 76 and Interstate 70 through Breezewood, Pennsylvania via U. The reason why this connection is not direct hearkens back to the requirements of the Federal-Aid Highway Act of Under Section c , interchange connections between a toll road and the Interstate Highway System could be constructed with either Federal-Aid highway funds or toll revenue; however, if Federal-Aid funds were used, the tolling authority and state department of transportation would have to enter into an agreement with the Federal Highway Authority to cease collecting tolls upon retirement of the bonds.
In addition, the PTC decided not to use its own revenue for constructing other direct interchanges, such as Interstate 81 in Carlisle and Interstate 99 in Bedford. There are no immediate plans to construct an Interstate 70 Breezewood bypass, so the strip of fast food, gas stations, and motels will remain a busy route for Interstate 70 motorists for some time to come.
I east merges with U. Beyond the Pennsylvania Turnpike spur linking I east with U. The I eastbound mainline makes a left turn from U.
I resumes along a freeway leading south from U. Weingroff that appeared in Public Roads. A sign in St. The Pennsylvania Turnpike today incorporates portions of both Interstate 70 and Interstate The section between Irwin Exit 67, near the U. Although the Turnpike did not have Interstate 70 shields on it when it opened, this portion of Interstate 70 and Interstate 76 could be considered the first Interstate highway.
However, this toll facility was not built with Interstate Highway Funds. The Interstate designation was added to the Turnpike well after the roadway opened. Charles County was the first Interstate Highway project to be awarded and to start construction contract awarded on August 2, , and construction began on August 13, In Kansas, a two-lane section of Interstate 70 U.
This section of Interstate 70 opened on November 14, The freeway occupies a narrow footprint as it ascends toward the top of the swell. The D "harbor route" alignment was preferred over the north-of-downtown alignment proposed in , as it would have required the removal of 3, dwelling units, four business buildings, and no churches for the D alignment, versus 5, dwelling units, 18 business buildings, and six churches for the northerly alignment. This map shows the original D expressway plan devised by the Baltimore City Department of Planning.
This illustration shows the major interchange between I, IN, and I that was proposed for the northeast corner of the Inner Harbor under the original D plan. View is toward the northwest. The consortium was comprised of J. The key differences between the Expressway Consultants plan and Darling's D plan were as follows: IN: Beginning at the I Southwest Expressway interchange, IN was to head northwest toward the Franklin-Mulberry alignment, then head west toward Leakin Park and the current alignment for I I The route was to enter the city as the Southwest Expressway, but was to continue on a straight line northeast toward Carroll Park then veer east in the area of Carey Street en route to the Inner Harbor.
I Beginning at I in the Fells Point neighborhood, I was to have been built along the eastern edge of the Inner Harbor, then north along President Street toward the current I alignment.
The Expressway Consultants alternative addressed concerns about routing the East-West Expressway along the northern edge of the Inner Harbor, including the need to fill in parts of the harbor. However, neither alternative addressed concerns about the effects of the I Inner Harbor bridge and approach viaducts in the Federal Hill and Fells Point neighborhoods. By the mids, groups favoring the D proposal and those favoring the Expressway Consultants proposal had reached an impasse.
This illustration shows the major interchange between I and I that was proposed for the eastern edge of the Inner Harbor under the Expressway Consultants alternative. This technique is commonplace in modern highway planning, but was a novel concept in the s.
In early , the UDCA published their reasoning for developing a new highway plan as follows: While environmental and social factors had been previously considered in expressway planning, it was not until major parts of urban Interstate roads were finished, or being finished in other cities, that their impact on the environment and socioeconomic structure of the cities could be assessed.
These impacts, which were more severe in fact than in plan, alerted city, state, and Federal officials to the need for a new approach to urban freeway design. In response to these concerns, the City of Baltimore and the Federal Highway Administration then the Bureau of Public Roads pioneered a technique of highway planning which included participation by the public in the planning stages of a project and consideration of public comments for proposed plans.
The task was to seek methods that would preserve the physical and environmental qualities of the city and at the same time provide the needed transportation network. Baltimore's solution was to establish a multi-disciplinary team consisting of experts in the fields of highway engineering, planning, architecture, and urban planning, as well as specialists in sociology, housing, and systems analysis. It was in this analysis that a southern bypass of the Inner Harbor area was first proposed for I, as well as a hybrid freeway-and-boulevard built from the southern bypass north along the western edge of the Inner Harbor to downtown shown in planning maps as the "Sharp-Leadenhall Corridor".
Although the early plans kept an "East-West Expressway" through downtown, the southern bypass theoretically was seen as a second "East-West Expressway. However, the proposed southerly bypass, along with the freeway-and-boulevard spur, would provide downtown access without having to build a new Interstate highway downtown.
The plan without the East-West Expressway through downtown, and only the southern bypass, became known as the "3-A" plan.
In its final report published in December , the UDCA team gave its blessing to the 3-A plan as follows: The 3-A System is based on the fundamental principle that the heart of the city, the Central Business District CBD and its immediate environs, should continue to serve as the center of commerce and culture of the Baltimore Metropolitan Area.
As such, the highway network should maximize accessibility to the CBD, but minimize impacts by routing "through" traffic around this area through other corridors. This principle dictates the separation of local CBD-destined traffic from "through" traffic and required major changes in the D System, including the following: Reduction in size and type of facility in the Inner City.
Boulevard was proposed which would ring the CBD and utilize existing at-grade city streets. Elimination of the I bridge across the Inner Harbor. I will be a spur from I serving traffic to and from the south of the city. I is to be a spur from IN serving traffic to and from the west, while I, when complete, will be a route between I and I serving traffic to and from the north and east, but also functioning as two spurs. An interchange was to have been built for I Franklin-Mulberry Expressway.
IN was redesignated I in I was canceled northwest of I in , and southeast of I in With this in mind, the UDCA, in conjunction with IN construction, planned to improve both parks with the construction of three swimming pools, 27 new miles of trails, tennis courts, baseball fields, picnic areas, and a daycare center.
In planning IN through Leakin and Gwynns Falls Parks, the UDCA team went a step further by proposing that the Federal government pay for 90 percent of the cost of improving both parks, which was the same percentage that the Federal government paid for Interstate highway construction. A final proposal outlined a spur Interstate utilizing a portion of the planned I corridor northwest from I to the section of Interstate Interstate 70 Home » Guides » Maryland » Interstate Route Numbering Committee meeting May 29, Go to Top.
Monocacy Boulevard and South Street see a folded diamond interchange with the freeway Exit 55 , east of the merge with Interstate It intersects Interstate 70 and U.
