  1. Bridge Rehabilitation W-14-082 Interstate 290 over CSX Railroad and 4 City Streets I-290 Viaduct Reconstruction

  2. What does the project consists of? $16.5 Million project to rehabilitate the bridge structure carrying I-290 over: CSX Railroad Grafton Street Franklin Street Shrewsbury Street Access road to commuter parking lots

  3. Overview of Affected Area

  4. Bridge Attributes • Consists of 11 spans • 1550 feet in length • Four lanes in each direction (3 travel lanes) • Carries 120,000 vehicles on an average day • Major regional roadway • Used heavily for intra-city trips • Built in 1958 (therefore it is 46 years old) • It has reached the end of its useful life

  5. What is wrong with the bridge? • Bridge deck is severely deteriorated and saturated with salt. • Steel I-Beams are undersized for today’s heavy trucks. • Damaged expansion joints have led to deterioration of concrete in the substructure. • Bridge railing does not meet current standards. • Cost to repair and maintain the bridge is becoming uneconomical.

  6. Ramifications If Project Is Not Done • Could potentially reduce travel lanes to reduce loading. • Increase the posting and restrict truck traffic from I-290. • Could lose a section of the bridge. • Could lead to more extensive/expensive substructure repairs. • In other words – • This issue has to be addressed!

  7. How are we going to fix the bridge? • Completely demolish the existing deck and railings. • Clean and paint structural steel at critical areas to protect against future corrosion. • Reinforce the steel I-beams with steel plates and other structural retrofits. • Repair concrete substructure. • Provide new deck. • Provide new railing. • Provide new expansion joints.

  8. The Big Question How are we going to keep traffic moving while we rebuild the bridge?

  9. Construction Staging Plan • 2 stages of construction • Construct the bridge in halves • Bridge consists of 2 separate structures, 1 eastbound and 1 westbound • Construct one structure at a time • Use remaining structure to carry 2 lanes of traffic in each direction • Close Shrewsbury Street off-ramp (phase 1) • Close both Grafton Street on-ramps and Summer Street on-ramp (both phases)

  10. Phase 1: Spring 2004 to Fall 2004 • All I-290 lanes and ramps open from Fall 2004 to Spring 2005 • Phase 2: Spring 2005 to Fall 2005 • Fall 2005 – substantial completion – all ramps and lanes open • Phase 3: Work on bridge substructure • (no impact on 290 traffic – little impact on local traffic) • Total of approximately 14-16 months of impact Construction Staging Plan (cont.)

  11. Getting the Word Out • Media campaign to encourage alternate routes • Local cable channel • Local newspaper • Local radio • Hotline – 508-752-8765 • City and MassHighway websites • Regional and local signage to encourage alternate routes – coordinate with City officials • Monthly CAC meetings – if necessary

  12. Parking • Coordinate with City on parking beneath I-290 • Rotating impacted areas • Identify alternate locations for parking

  13. Ramp Closures & Detour Routes

  14. Grafton Street EB on-ramps closed • East Central Street WB on-ramp closed • Summer Street WB on-ramp closed • Shrewsbury Street EB off-ramp closed Ramp Closures – Stage 1 2004

  15. Grafton Street EB on-ramps closed • East Central Street WB on-ramp closed • Summer Street WB on-ramp closed • Shrewsbury Street EB off-ramp open Ramp Closures – Stage 2 2005
