Iway
From Wikipedia, the free encyclopedia
Iway is the $610 million project by the Rhode Island Department of Transportation (RIDOT) to relocate the I-195 and I-95 intersection in Providence, Rhode Island, USA[1]

[edit] Project improvements
- The project will free up space in downtown Providence and the Jewelry District.
- Renovate India Point Park and construct a 50 foot wide pedestrian bridge.[2]
- Signature arch bridge over the Providence River.
- Improved highway flow, access, and safety. The existing intersection was not built for today's traffic standards. Moreover, the cement supports have been deteriorating to the point that steel buttresses are needed to reinforce the intersection's many bridges. Also, the existing lane alignment is dangerous and promotes congestion as lane shifts are often required to avoid an exit-only lane.[3]
[edit] Current Status
RIDOT on May 22, 2008 closed Exit 3 (Gano Street) from I-195 East and simultaneously opened a new Exit 2, which leads to India Street. At the end of the ramp, motorists can turn left toward Gano Street. Later in the summer, RIDOT plans to open India Street to allow a right turn at the ramp, which will provide access to South Water Street.
RIDOT intends to close Exit 20 from I-95 North on June 4, 2008. This will require all traffic from I-95 North to I-195 East to use the Iway. The closure will mean a loss of access to Exits 1 and 2 on the old I-195. Motorists will be offered several suggested detours. Information is posted on RIDOT's website, including color coded maps of the suggested routes. [4]
The on-ramp from I-95 North to I-195 East opened on November 4, 2007 under Exit 19. This provides access to Exit 3 (Gano Street/India Street) and I-195 East toward East Providence and Massachusetts. The old ramp, Exit 20, remains open for access to I-195 East Exits 1 or 2, as well as to continue east on I-195 toward Massachusetts. Other existing ramps remain in service; however there will be a phase-in of new highway connections and ramps in 2008 and 2009.
The first few days of the Iway being opened caused lengthy delays for motorists on I-95 South to I-195 East.This was alleviated by several steps RIDOT took. These included combining two on-ramps into one at their merge point with I-195 East, making minor lane adjustments, and a public education campaign to encourage people to get onto I-95 North and then the Iway as opposed to using exits on the old stretch of I-195 where backups were occurring. These changes shifted traffic to the Iway which had access capacity. In three days traffic was reduced to original evening congestion levels. By the end of the week, congestion had lessened from original levels.[5]
RIDOT also opened an on-ramp to the Iway from South Main Street. The ramp's opening was accelerated from original plans and was opened on a temporary basis in the evenings beginning on November 9, 2007. On December 19, 2007, the ramp was open full time.[6]
The opening of the Iway ramp has eased congestion on I-95 North during the afternoon commute. Originally traffic backed up each evening for approximately 2.2 miles. Traffic backups on this part of I-95 North are unusual except in times of adverse weather or accidents.
RIDOT on April 4, 2008 announced a number of changes scheduled for the coming year. The most significant of these is the planned opening of a new ramp from I-95 South to I-195 East by the end of the year. This exit ramp will be shifted from the left to the right, which should reduce congestion from weaving traffic. The new ramp will arch up and over the highway, meeting the section of the Iway that was opened in 2007. Detailed information about all Iway-related changes for the coming year can be found at RIDOT's website
[edit] History
Back in the 1980s, RIDOT reviewed many plans to deal with the aging section of I-195 in Providence, which was built in the 1950s. Along with having to complete numerous repairs on one of the busiest stretches of highway in Rhode Island, traffic volumes had increased tremendously over the years. The highway designed for 75,000 vehicles a day now carries more than 160,000 cars daily.
The old design had other problems. Tight curves, left-hand exits and closely spaced exits have contributed to excessive congestion on the highway, which spills over onto adjacent highways, causing delays for motorists on I-95, the Route 6/10 connector, and on city streets.
As RIDOT worked on the Iway’s Environmental Impact Statement (EIS) in the early 1990s, the highway’s problems were put to paper. The EIS noted deteriorated bridges, substandard roadway alignments, sharp curves and substandard shoulder widths. During the initial stages of the project, DOT worked with the Rhode Island School of Design to include studies of the Iway in its "Project Providence," an exploration of the city through computer visualization.
RIDOT looked at three alternatives before choosing the one now being built. An alignment just to the north of the current highway was not selected as it would have corrected only the congestion and tight curves on I-195 itself. It would not deal with the weaving motorists face due to closely spaced exits at the highway interchange, it would not have addressed better access to the Eddy Street hospitals campus, and it would have created only limited opportunities for redevelopment as outlined in the Old Harbor Plan. The plan outlines how the land occupied by the existing highway will be reused.
Another idea that was considered was a no-build alternative, one in which the existing alignment would be reconstructed. This would have addressed problems with deteriorated structures, but done nothing about the congestion, weaving conflicts and existing safety hazards. Additionally, traffic would have been severely impacted during construction.
Consideration of these choices led RIDOT to choose the alignment south of the Fox Point Hurricane Barrier. Safety problems and congestion issues could be addressed, and the removal of the old highway would allow for significant redevelopment of the Providence waterfront and fuller implementation of the Old Harbor Plan. Also, the redevelopment would complement other projects including the construction of Memorial Boulevard, Waterplace Park and the Riverwalk system, and the Capital Center projects.
[edit] Opening-day ceremonies
The opening of the Iway was preceded by a public walk on the Iway on October 20, 2007. An estimated 10,000 people attended the event from 9 a.m. to noon. Visitors started lining up one hour before the event start time and RIDOT extended the event by about one hour. Visitors traveled to the site on RIPTA buses from one of two satellite parking locations in Providence, from the Johnson & Wales University Harborside Campus and from the State Offices campus. Once there they received a commemorative program and walked the length of the new Providence River Bridge was well as approach ramps on both the east and west side of the bridge. Copies of the program can be obtained by contacting RIDOT Customer Service at 401-222-2450 or viewed on-line.
[edit] Iway podcasts
On October 1, 2007, RIDOT began releasing video podcasts of the Iway project. New "episodes" were released weekly. There are a total of 12 episodes, six in English and six in Spanish. The podcasts are available for viewing on a computer or downloading to a personal video player such as an iPod. The podcasts also are available on RIDOT's website, YouTube and iTunes.
The podcasts tell the story of how the Iway came to be. It includes various computer-enhanced images to show the new highway on the existing landscape. There are also animations that represent a virtual drive on the new highway. Information on the construction of the new Providence River Bridge, and its transport by barge from Quonset to Providence.
