The existing, obsolete pedestrian bridge next to the historic larger span was be replaced with a wider, ADA compliant bridge[3] that better complements the arches of the older structure. The old and new pedestrian bridges both were designed to span Storrow Drive, connecting from near Charles/MGH (MBTA station) to the Charles River Esplanade near the Longfellow Bridge. The new bridge deck arch is contemporary in appearance and very transparent, in order to not obstruct views of the historic Longfellow Bridge, the river, and parkland. The slender main steel arch span is approximately {{convert|222|ft|m}} long.[4] The approach ramps follow a similar architectural language and appear to float over the landscape before landing next to the river. Huge concrete ramps anchor each end of the bridge. Design and constructionThe Frances Appleton Bridge was originally scheduled for completion in 2017, at an estimated cost of $12.5 million.[4] Bridge architect Miguel Rosales of Boston-based transportation architects Rosales + Partners provided the conceptual design, bridge architecture, and aesthetic lighting design. Preliminary design engineering was performed by Jacobs Engineering. STV, Inc will be the final design engineer and engineer of record. The design/build phase of the bridge was be completed by the joint venture team of contractors White-Skanska-Consigli, and overseen by the Massachusetts Department of Transportation.[3] The bridge opened on August 31, 2018,[5] and is owned by the Massachusetts Department of Conservation and Recreation. {{-}}References{{Portal|Bridges}}1. ^{{cite web| last=MassDOT |title=Longfellow Bridge|url=http://www.massdot.state.ma.us/charlesriverbridges/LongfellowBridge.aspx|accessdate=26 August 2018}} 2. ^{{cite web| last=The Commonwealth of Massachusetts|title=Session Law|url=https://malegislature.gov/Laws/SessionLaws/Acts/2014/Chapter108|accessdate=15 July 2015}} 3. ^1 {{cite web|last=MassDOT|title=Longfellow Bridge|url=http://www.massdot.state.ma.us/charlesriverbridges/LongfellowBridge.aspx|accessdate=31 July 2013}} 4. ^1 2 {{cite news|last1=Murphy|first1=Dan|title=New Foot Bridge to be Next to Longfellow|url=http://beaconhilltimes.com/2015/07/22/new-foot-bridge-to-be-next-to-longfellow/|accessdate=2015-07-24|work=Beacon Hill Times|publisher=Independent Newspaper Group|date=July 22, 2015}} 5. ^1 {{cite tweet|user=MassDot|number=1035567145239887873|date=31 August 2018|title=#Boston: new Fanny Appleton Pedestrian Bridge now open ahead of schedule! @MassDCR}} External links{{Commons category|Frances Appleton Bridge}}
